2 page FRACTIONS Many of the students recommended for JUMP do not know any times tables when they start the program. It might seem pointless, therefore, to teach these students fractions right away: they have a very poor sense of numbers and cannot be expected to find the lowest common denominator of a pair of fractions readily. I have found, however, with students who have fallen behind, that fractions are an ideal place to start. With fractions, complex operations can be reduced to steps any student can reproduce. In mastering these operations, even the most delayed students in JUMP have shown remarkable improvements in memory, concentration, and numerical and conceptual ability. To teach this unit effectively you should bear in mind that its purpose is as much psychological as mathematical: the material is designed to train a student's attention and build confidence. Students who learn how to multiply and divide in the course of performing more difficult operations are motivated to remember their times tables. As well, a great deal of conceptual work is also learned while performing the apparently mechanical procedures of this unit. Students learn to recognize patterns, select appropriate algorithms and carry out complex sequences of operations. The goal of even the most mechanical exercise in the unit is to prepare children for more advanced conceptual mathematics. In a recent pilot, all of the teachers who used the fractions unit acknowledged on a survey that they had greatly underestimated their weaker students in over ten categories, including enthusiasm, concentration, ability to remember number facts and ability to keep up with faster students. The teachers also acknowledged that the gains their students made in mathematics spilled over into other subjects. NOTE: This is not a complete unit on fractions. For exercises that teach the concepts underlying the operations covered in this unit (with pictures and concrete materials) see the Grade Specific JUMP Workbooks. See also The Development of Concepts section below. The Development of Concepts As your students master the operations in this unit, teach them to articulate the general principles underlying the operations. You might, for instance, eventually write out simple phrases on their homework that they should memorize. For example: To add two fractions with the same denominator, you just add the numerators (you are adding up the number of pieces). The denominator stays the same because it tells you how many pieces the pies are cut into (the piece size). The bigger the denominator, the more pieces in the pie, so the smaller the piece. When the denominators are different, you must change one or both before you can add the fractions etc
3 page To help your student remember an operation and articulate how it works, the following exercise is very effective. Write down several examples of the operation in which you have made some errors. For instance, if you have covered section F- of the manual you might write, change both denominators change both denominators change one denominator 7 7 Ask your student to find your mistakes, and explain what you did wrong. Students enjoy this: they work very hard to find your mistakes (and usually keep reminding you that you made them). IMPORTANT NOTE: Students in Ontario must demonstrate a solid understanding of mathematical concepts to meet the requirements of the elementary curriculum: they must be capable of explaining how they found solutions to problems and of applying their knowledge to novel situations. Why, then, in this fractions unit, are operations introduced in entirely mechanical steps (and why at a level beyond current expectations for elementary students)? There is a contagious enthusiasm that spreads through a class when students believe they are capable of learning material beyond their grade level (see The Myth of Ability for a description of how JUMP works in a classroom). A teacher will find it hard to generate this kind of enthusiasm if they allow even a third of their class to feel they have no aptitude for mathematics. The fractions unit is designed specifically to help a teacher capture the attention of their weakest students and to build the basic mathematical skills those students need to progress to more advance conceptual work. None of the exercises in this unit require a mastery of English or of higher-order concepts. Students who speak English as a second language (a growing part of the population in many schools), students who are delayed in reading or writing, and students who have fallen behind academically are allowed the same chance to succeed as their peers. To do well on the Tests (sstarting page ), students must simply perform the various operations introduced in the unit correctly. The units that follow the unit (contained in JUMP s grade specific workbooks and available separately) gradually introduce more conceptual work. JUMP students who complete this unit must score 80% or higher on the Test before they move on to new units. The Test does not completely test a student s understanding of fractions. The point of the test is largely psychological: students who learn to perform complex calculations with fractions, and who do well on the test, show remarkable improvements in confidence, concentration, and numerical ability. This has been demonstrated in several elementary classrooms, with more than 1000 students. How To Use The Unit Student Worksheets The Student Workbook (under separate cover) is meant to accompany and support this Teaching Manual booklet. Before you start using the student worksheets, please read the following instructions / guidelines so you ll be sure to extract the greatest benefit from your time:
4 page The worksheets are intended to coincide with the specific units presented in the JUMP Teaching Manual. Each sheet has a specific code in the top right-hand corner. For example: This letter indicates the specific unit (e.g. F =, PA = Patterns, etc) being covered F- B This number corresponds to the manual section (e.g. F- teaches Changing One Denominator ) This letter gives the worksheet s level of difficulty (e.g. A = easiest, B = intermediate, C = advanced, etc). The main distinction between levels is in the times tables used. If your student only knows s, s and s, it s important to stick to the A-level sheets. If your student knows their higher tables, you can give them the additional worksheets for bonus work. The final Tests reflect a similar breakdown in terms of times table knowledge. Please test your students appropriately. In the Homework section, you will notice some sheets have a code ending in HW. This indicates a sample homework sheet. Notice that these sheets cover not only the new work taught in the indicated section, but also include questions on previous sections. It s important that you follow this structure when designing homework for your student it gives them a chance to practise and reinforce earlier skills, and also to demonstrate the progress they re making. Most importantly, this worksheet booklet shouldn t be used in isolation. It is mainly intended as a starting point and guideline for tutors and teachers. You may wish to supplement the sheets we ve provided with additional questions customized to address specific trouble areas you encounter with your students.
5 page Section F-1: Counting First check if your student can count on one hand by twos, threes and fives. If they can t, you will have to teach them. I ve found the best way to do this is to draw a hand like this: 8 10 Have your student practise for a minute or two with the diagram, then without. When your student can count by twos, threes and fives, teach them to multiply using their fingers, as follows: The number you reach is the answer. Give your student practice with questions like: x count on your fingers by this number until you have this many fingers up. x = x = x = x = x = x = Point out that x means: add three, two times (that s what you are doing as you count up on your fingers). Don t belabour this point though you can always explain it in more depth when your student is further into the unit. Your student should be able to count and multiply with ease by twos, threes and fives on one hand before you teach the next section. As it is important to create a sense of momentum in your lessons (while still teaching by steps and allowing lots of repetition), you shouldn't expect a more delayed student to learn any table other than the fours (on one hand) as you progress through the rest of the unit. After your student has written the Test you can introduce higher tables. (With a more motivated or knowledgeable student, you can demand more: you might draw a new hand on their homework every few weeks and ask them to memorize it. You might also assign questions where they are required to use higher tables.) IMPORTANT NOTE: Do not move on until all of your students have gotten 100% on the diagnostic quiz (Question ) on worksheet F-1 (continued). Make sure your students can add and subtract one digit numbers as taught in the Appendix. Students can learn the skills required to do well in this unit very quickly do not move on until you have taught the skills covered in this section. Any time you see a stop sign ( ), it is a signal for you to stop and verify that all your students have grasped the skill before you move on.
6 page Section F-: Naming Explain how to represent a fraction. Step 1: Count the number of shaded regions 8 Step : Count the number of pieces the pie is cut into Remember, each step should be taught separately (allowing for repetition) unless your student is very quick. Here are some questions your student can try. What fraction of each figure is shaded? Teach your student how to draw 1 and 1 with circles. Teach them how to draw 1 as follows: Ask your student how they would draw 1 and 1 in a square box. Make sure they know that in drawing a fraction, you have to make all the pieces the same size. For instance, the following is not a good example of 1 :
7 page 7 Your student should be able to recognize when a shaded piece of pie is less than 1 of a pie. To see that the fraction is less than 1, continue one of the lines. Section F-: Adding Two With the Same Denominator Rule: Add the numerator and leave the denominator the same. For example, 1 + = 1 piece plus pieces gives pieces Make sure your student knows why the denominator does not change: the pie is still cut into pieces you are still adding up 1 size pieces. Allow for lots of practice. Only introduce one step at a time. Whenever possible, you should allow the student to figure out how to extend a concept to a case they haven t seen. This is easy to do with the addition of fractions. Ask your student what they might do if: There were three fractions with the same denominator? =?
8 page 8 (If your student guesses what to do in this case, point out that they are smart enough to figure out mathematical rules by themselves. It is essential that you make your student feel intelligent and capable right from the first lesson.) If they had subtraction? - 1 =? Demonstrate this with a picture: If they had mixed addition and subtraction? =? taking away 1 leaves Section F-: Adding With Different Denominators If the denominators are different, then you can t compare piece sizes it s not clear how to add fractions with different denominators =? Tell your student that after you have shown them how the operation works with pictures you will show them a much easier method that they cannot fail to perform. (You should, however, return to this sort of pictorial explanation when your student has fully mastered the operation). Solution: Cut each of the two pieces in the first pie into three, and cut each of the three pieces in the second pie into two. This will give the same number of pieces in each because x = x =
9 page 9 + = Draw the above picture, and ask your student to write the new fractions corresponding to the way pies are now cut. Make sure they notice that 1 is the same as of the pie, and that 1 is the same as (and one out of three pieces is the same as two out of six). Once you have discussed this, your student can perform the addition. The one thing the student should take away from this explanation is that to produce pieces of the same size in both pies (which is necessary for adding fractions), one has to cut each pie into smaller pieces. (For more advanced students: the number of pieces you need to cut both pies into is equal to the lowest common multiple of the denominators see Section F-9). Tell your student you will now teach them a very easy way of changing the number of pieces the pie is cut into without having to draw the picture. Step 1: Multiply each denominator by the other one. The numerator also has to be multiplied, because now you are getting more pieces: x x x x Have your student practise this step before you go on. The student should just practise setting the right numbers in the right places. Remember you can make this step easier if necessary by having the student move one denominator at a time. Step : Perform the multiplication. x x = + x x Practise Step 1, then Step 1 and Step together, before you go on. Step : Perform the addition. + = Now have the student practise all three steps.
10 page 10 For students who know higher times tables, gradually mix in higher denominators like and 7 (make sure the smaller denominator does not divide the larger). NOTE: Two numbers are relatively prime if their least-common multiple (the lowest number they both divide into evenly) is their product. For instance, and are relatively prime but and are not (since the product of and is, while their least common multiple is 1). The method of adding fractions taught in this section is only really efficient for fractions whose denominators are relatively prime (as is the case for all of the examples directly above). For other cases, for instance when one denominator divides into the other or when both denominators divide into a number that is smaller than their product, more efficient methods can be found in sections F- and F-9. Section F-: Changing One Denominator Tell your student that sometimes you don t have to change both denominators (i.e. there s a short-cut) when you add fractions. How can you tell when you can do less work? Step 1: Check to see if the smaller denominator divides into the larger. Count up on your fingers by the smaller denominator and see if you hit the larger denominator if you do, the number of fingers you have up is what you multiply the smaller denominator by: = x x 10 Counting up by twos you hit 10. You have fingers up. This means x = 10 Multiply the smaller denominator by the number of fingers you have up Give lots of practice at this step before you move on. Step : Perform the multiplication. x = + 1 x Step : Perform the addition. + 1 =
11 page 11 Extra: Ask your student how they would do 1-1 = 10 Here are some sample questions you can use during this lesson: (1) () + 1 () () () () (7) + 1 (8) (9) 7 + (10) 1-1 (11) - 1 (1) Note: If you think your student might have trouble with this section, you should start with the following exercise: tell your student that the number "goes into" or "divides" the numbers they say when they are counting up by twos (i.e. divides,,, 8, etc). Write several numbers between and 10 in a column and ask your student to write "yes" beside the numbers that goes into, and "no" beside the others. When your student has mastered this step, repeat the exercise with numbers between and 1 (for counting by threes) and numbers between and divisible by (for counting by fives). Tell your student that when they are adding fractions, they should always check to see if the smaller denominator divides into the larger; when this is the case they only have to change the smaller denominator. Section F-: Distinguishing Among the Three Methods Taught Thus Far This is an important section. For many students, it may be the first time they are taught how to decide which of several algorithms they should use to perform an operation. Step 1: As a warm-up exercise, write a number on the board. Have your student tell you whether they say that number while counting by. Repeat the exercise but counting by s and then by s. Do not move on until all of your students have gotten 100% on the diagnostic quiz (Questions 1,, & on worksheet F- A). Step : Identify the lesser denominator. Step : Count up by that number and see if you hit the greater denominator (i.e. see if the lesser divides or goes into the greater evenly). If yes, write yes. If not, write no. In other words, the student is identifying whether or not they will have to change one fraction (short-cut) or both fractions (no short-cut) before adding. Practise these steps on a variety of different pairs of fractions before going on.
12 page 1 Note on F- B, Question : If the student has written same, add the fractions using the procedure in F-. If they have written no then follow the procedure in Section F-, and if they have written yes then follow the procedure in F-. Typical Exercise: (1) 1 + () + 1 () Section F-7: Adding Three. Let your student know that this is an enriched unit. Adding triple fractions is normally not covered until Grade or 7. Give questions where two smaller denominators go into the larger, i.e x x + 1 x x = Note: When you first teach this section, always place the fractions with the two lowest denominators first. After your student has mastered this, you can change the order and ask them to identify which denominators have to be changed. Here are some sample questions you can use during this lesson: (1) () () Section F-8: Equivalent and Reducing First check to see if your student knows how to divide by a single-digit number. If not, teach them as follows: 1 =? Count up by the number that comes after the division sign, until you reach the number in front of the sign; the number of fingers you have up is the answer; i.e. divides 1 five times, because it takes five s to add up to 1. Give lots of practice. Then explain to your student that the same fraction can have different representations:
13 page 1 For instance, with 1 of a pie and of a pie you get the same amount of pie. Each fraction has a representation in the smallest possible whole numbers. Finding this representation is called reducing the fraction. To check whether a fraction can be represented with smaller numbers, your student should first check if the numerator divides into the denominator. Step 1: Count up by the numerator to see if it divides into the denominator 1 Step : If yes, divide both the numerator and the denominator of the fraction by the numerator: = 1 1 Some students will need a good deal of practice with step 1. You might give your student a sheet of questions on which they simply have to count up by the numerator, checking to see if they say the denominator as they count. Once your student has mastered the steps above, let them know that if the numerator of a fraction does not divide the denominator, they should still check to see if any smaller number divides both. If they find a number that goes into the numerator and the denominator, they should reduce the fraction as follows: = You might start by giving your student hints. You might say, for instance, The numerator and denominator of this fraction either divide by or by. Check which one works. Here are some sample questions you can use during this lesson: Division: = 1 = 8 = 1 = 1 = = 10 = 0 =
14 page 1 Reducing fractions (easier): = = = = = = Reducing fractions (harder): = = 8 = 8 = = 9 = Note: If your student has just learned to multiply, only ask them to reduce fractions where the numerator and denominator divide by, or. You should give them the same questions repeatedly for homework as it may take them some time to get used to reducing. Section F-9: Finding the Lowest Common Denominator (This section should only be taught to second year JUMP students or to very advanced first years.) The lowest common multiple (LCM) of two numbers is the lowest number that both divide into evenly. For instance, the lowest common multiple of and is 1. Notice that the lowest common multiple of and is lower than their product ( x = ). But with other numbers, say and, the lowest common multiple is the product. To find the lowest common multiple of a pair of numbers, simply count up by the larger number and keep checking if the smaller divides into the result. Example: and. Count up by sixes. does not go into. Keep counting up. 1 goes into 1. Therefore, LCM = 1 Example: and. Count up by threes. does not go into. Keep counting up. goes into. Therefore, LCM = Example: and 10. Count up by tens. 10 goes into 10. Therefore, LCM = 10 By counting up, have your student find the LCM of the following pairs. Also have them say whether the LCM is equal to the product, or less than the product. and and 8 and
15 page 1 and 10 and 10 and 9 and 10 and and and 8 8 and 10 and 7 The method of adding fractions we taught in sections F- to F- doesn t always yield a final denominator that is the LCM of the two denominators; by our method the student would add 1 both fractions as follows: and x x + 10 x x 10 can be reduced (see Section F-8) to 1 by changing If the student thinks that the LCM of a pair of denominators may be lower than the product, then (to avoid having to reduce the answer) they should proceed as follows: To find the LCM, count up by the larger denominator (in this case ) until you reach a number that the smaller denominator divides into. Counting by sixes you get 1, and you can stop counting there because divides into 1, so the student can use 1 as the denominator: x x + x x Make sure your student knows the LCM is also called the lowest common denominator. Your student should try these questions: This method will also work for triple fractions Tell the student to count up by the larger denominator, and at each stage check if the smaller denominators divide the number you have reached. For instance: two 10s are 0, but does not divide 0, so the student should keep counting by tens. Three 10s are 0, and and both divide 0, so the student should use 0 as the denominator. Here are some sample (Grade 8 level) questions you can use during this lesson: (1) () ()
16 page 1 Section F-10: Mixed and Improper If the numerator of a fraction is bigger than the denominator, the fraction is called an improper fraction. Any improper fraction can also be written as a mixed fraction, that is, as a combination of a whole number and a fraction. For instance: = 1 1 You can explain these two ways of writing a fraction with a picture. or 1 1 Three half-size pieces of a pie are the same as one whole pie, plus an extra half. How to write a fraction as an improper fraction: Example: 7 Step 1: How many pieces are shaded? Answer: 7. Put this number in the numerator. Step : How many pieces is each pie cut into? Answer:. Put this number in the denominator. (Even though you have more than one pie, the piece size doesn t change you still have third-size pieces in each pie 7 altogether.) How to write a fraction as a mixed fraction: Example: 1
17 page 17 Step 1: How many whole pies are there? Answer:. Write this down as a whole number. Step : Write down what fraction of a pie you have in the last pie. Give your student lots of practice in the two ways of writing a fraction. Here are some examples you might use: 11 or or or 1 Your student should be able to draw simple, mixed fractions like 1 1, 1, 1 1, 1, 1 1, 1. Your student should also be able to decide, in simple cases, which of two mixed fractions is larger. For instance: 1 or or 1 1 or 1 1 Your student should be able to explain how they can tell when a fraction represents more than a whole pie: i.e. they should be able to say when the top (or numerator) is larger than the bottom (or denominator) you have more than one pie. As a test, write out several fractions and ask your student to identify the fractions that represent more than one whole pie. For instance, 7 1
18 page 18 IMPORTANT NOTE: GRADE & TEACHERS STOP HERE!! If you are a Grade - classroom teacher participating in the JUMP In-Class program, you are only expected to teach up to section F-10. When you are sure your students understand the material in Sections F-1 to F10 you can give them the Pre-Test for Workbooks and, and then the Test for Workbooks and. Grade - teachers should complete the entire unit and give the Pre and Actual Tests for Workbooks and. (All tests are included at the end of this Manual) Section F-11: Converting (Without Pictures) Converting mixed fractions into improper fractions: Example: Step : + 1 = 7 1 = 7 Step Step x Step 1: Multiply the whole number by the denominator (i.e. x = ). To explain this step, point out that in the two whole pies (each cut into three pieces), there are six pieces. Step : Add the number you got in the last step to the numerator. Put the sum in the numerator of your improper fraction. (To explain this step, point out that in the one-third pie you have one piece which has to be added to the six pieces in the two whole pies, giving seven pieces altogether.) Step : Write the denominator of the mixed fraction in the denominator of the improper fraction. (The two fractions have the same denominator because the piece size is still one-third.) Here are some sample questions you can use during this lesson: 1 = 1 = 1 = 1 = = 1 1 = 1 = = = = = 1 = Section F-1: Converting Converting improper fractions into mixed fractions. First, you may have to teach your student how to divide when the divisor doesn t go evenly into the number being divided:
19 page 19 Example: 9 Step 1: Count up on your fingers by the divisor (i.e., ) until you reach a number just below the number being divided (i.e., 9). 8 Stop here If the student has trouble knowing when they should stop counting up, practise this step with various examples: If your student is really struggling with this step, write the numbers from 1 to 10 and circle the numbers divisible by. This will help your student see when to stop counting. Repeat this with the numbers between 1 and 1 (for counting by threes) and 1 and (for counting by fives). Step : Write the number of fingers you have up on top of the division sign: 9 Step : Write the number you reached on your fingers below the number being divided: 9 8 Step : Subtract to find the remainder: R Explain that the answer on top means that fits into 9 four times with 1 left over. You might draw a picture to illustrate this: remainder 1 How to convert an improper fraction into a mixed fraction: Step 1: Rewrite the fraction as a division statement: 9 9
20 page 0 Have the student practise putting the right number in the right place. Step : Do the long division. Your student should know how to do this from the previous section: R Step : Use the answer to the division problem to write the mixed fraction: 9 = R 1 After your student has learned to convert improper fractions to mixed fractions, teach them to estimate how many whole pies an improper fraction represents. For instance 7 is at least two whole pies because divides into 7 two times (the remainder, 1, is the number of fractional pieces in the last pie plate). Your student should be able to say, in simple cases, which of two improper fractions is larger. For instance, 7 11 is larger than because in the first case you have at least three whole pies, and in the latter, two. They should also be able to say when an improper fraction is bigger than a whole number. For instance, 7 is bigger than. Finally, your student should know that an improper fraction is always bigger than a proper fraction. You might write out several pairs and have them identify the larger; for instance, / and 7 /. Here are some sample questions you can use during this lesson: = 7 = 7 = 9 = 11 = 9 = 1 = 1 = = 17 = 11 = 17 = Note: Maggie Licata (JUMP s former Executive Director) suggested a method for converting improper fractions to mixed fractions which I think is easier than the one I give above (her method also enables students to do the conversions in their heads). If you use the following method, you should still, at some point, teach your student how to do long division by the method above.
21 page 1 Change 9 to a mixed fraction: Step 1: Count by the denominator until you reach a number just below the number being divided. (This is just step 1, as outlined above) Step : Write the number of fingers you have raised (i.e. four fingers) as a whole number: 9 = Step : Write the numerator of the original fraction beside the whole number: 9 = Step : Multiply the whole number by the denominator: x = 8 Step : Subtract the result of step from the denominator of the improper fraction: 9-8 = 1 Step : The answer from step is the numerator of the mixed fraction: 9 = 1 If your student has trouble with step, teach them to subtract as follows (see also the Appendix): 17-1 =? Step 1: Say the second number ("1") with your fist closed. Step : Raising one finger at a time, count until you reach the first number (i.e. the student raises one finger when they say "1" and another when they say "17"). The number of fingers you have up is the answer. Give your student lots of practice at this. (Eventually you can use fairly large numbers like to boost your student's confidence. Make sure the numbers you pick aren't too widely separated: for numbers that have a difference greater than 10, it is better to subtract by lining the numbers up in the traditional way.)
22 page Section F-1: Adding Mixed Converting fractions to improper fractions, then adding them. Example: First, convert the fractions to improper fractions (see Section F-10): = + 9 Now add the fractions (as taught in F- to F-): = + 9 = x x + 9 = + 9 = 1 Here are some sample questions you can use during this lesson: = = = = = + 1 = = + 1 = Note: There is a method of adding fractions that is more efficient than the one taught above when the whole numbers or the denominators of the fractions are large. If your student finds fractions easy, you might teach them the following method (otherwise wait until your student has completed several other units of the manual). Add: Step 1: Make the denominators of the fractions the same (as you would if you were simply adding the fractions): x x + 1 x x 8 + Step : Add the whole numbers (8 and ) and the fractions ( and as a single mixed fraction: ) separately, but write your answer 8 + 1
23 page In some cases, the fractional part of the answer may be an improper fraction. For instance: x x + x x In this case, your student should change their answer as follows: Step 1: Rewrite your answer as the sum of a whole number and a fraction: 1 7 = Step : Rewrite the improper fraction as a mixed fraction (as taught in Section F-1): Step : Add: = = 1 1 Section F-1: Comparing First teach your student the meaning of the greater than (>) and less than (<) signs. Tell them the arrow should always point from the larger number to the smaller number. Example: > 1 Two is greater than one. < Two is less than three Give the student practice filling in the sign with whole numbers. Example: 7? 9 7 < 9 Now, tell your student that to compare the size of two fractions you simply have to convert the fractions to the same denominator. The fraction with the larger numerator is the larger fraction. Example:? x? < x Note: If you would prefer not to teach your student about inequalities at this stage, you could simply ask them to circle the bigger fraction.
24 page Section F-1: Word Problems Here are some word problems from a Grade 7 book you could try: 1. Ken ate 8 of a pizza and Nola ate 1. What fraction of the pizza was eaten?. On Monday Mike ran for 1 hour in the morning and 1 hour in the afternoon. What fraction of an hour did Mike run on Monday?. Over one supper hour Carl used 1 of a container of tomatoes, and 1 of a container of olives. How many containers of toppings did he use? Give your students other questions of this sort. NOTE: Your student may now write the Fraction Test. Please use Pre-Test for Workbooks & (page ) as practice and Test for Workbooks & (page 8) as a final test. The Pre-Test & Test for Workbooks & are intended for students in grade or. If your student scores 80% or higher, they can move on. If they don t score 80% or higher, review the material they had trouble with and let them write the test again. (Make sure you let your student know, before you give them the test, that they can write it as many times as they need to.) Let your student know that the material in the test goes up to a Grade -7 level.

45 page Addition (Where one number is a single digit) Example: 1 + = Step 1: Say the greater number (1) with your fist closed. Step : Count up by ones raising first your thumb, then one finger at a time until you have the same number of fingers up as the lower number. Step : The number you say when you have the second number of fingers up is the answer (in this case you say 19 when you have three fingers up, so 19 is the sum of 1 & ) A great bonus question would be to add a multi digit number to a single digit number (e.g ). Just make sure your student can count high numbers. Subtraction (Where the answer is a single digit) Example: 11 8 = Step 1: Say the lesser number (8) with your fist closed. Step : Count up by ones raising first your thumb, then one finger at a time until you have reached the higher number (11). Step : The number of fingers you have up when you reach the final number is the answer (in this case you have three fingers up, so three is the difference between 8 & 11) A great bonus question would be double or triple digit subtractions whose difference is a single digit (e.g. -8). Just make sure your student can count high numbers.
