1 NC Level Objectives I can use language such as 'greater', 'smaller', 'heavier' or 'lighter' to compare quantities (FS) AfL Questions for assessing Strand Six : Measuring AfL questions from RF For objectives from Foundation Stage please refer to the Foundation stage curriculum Level 1 I can estimate, measure, weigh and compare objects, choosing and using suitable uniform nonstandard or standard units & measuring instruments (eg lever balance, metre stick, measuring jug) (1) For objectives from Foundation Stage please refer to the Foundation stage curriculum Which of these three objects do you think will be the lightest? Which do you think will be the heaviest? Which will you compare first? What else will you have to do to check if you have put them in order from lightest to heaviest? Which of the containers do you think will hold most? How many cups of water do you think it will take to fill the biggest jug? How do you know how much the biggest jug holds? Where do you start to measure the width of the hall? How many metres wide do you think the hall is? Write your guess on a piece of paper. Measure to halfway. Do you want to guess again? How many cubes balanced the tennis ball? How did you know when you had found the correct weight? Did you think the jug or the mug would hold more? How much more? What did you do to measure as carefully as you could? How do you know that the measurement is correct? Where do you start to measure the length of the carpet? Ann measured the height of these two dolls in blocks. How many blocks taller is the large doll? Is this stick longer or shorter than this straw? How do you know? Is the red parcel heavier than this other one? How do you know? Does this container hold more than this other one? How do you know? Which of these three containers holds the most water? How do you know? How could you check? Which of these objects are sensible to use for measuring? Why? What sort of measuring could you use them for? Would it be fair to measure with...? Why or why not? Estimate how many art-straws will fit across this table. How many of the long paintbrushes will fit across the table? Why do you think that there will be fewer paintbrushes? What did know that helped you to estimate? Before you measure, what are the important things to remember about measuring? Five children used cubes to balance one of their shoes. This table shows the number of cubes they needed.

2 Whose shoe is heaviest? Whose shoe is two cubes lighter than Gareth's shoe? I can use vocabulary related to time; order days of the week and months; (1) I can read the time to the hour and half hour (1) What day is it today? So what will tomorrow be? Which are the weekend days? Which days are we at school? Look at these pictures. Point to a picture which shows something that you think happened in the morning. Point to a picture which shows something that you think happened in the afternoon. Point to a picture which shows something that you think happened in the evening. What month is your birthday? Is it in the summer? Which month comes after March? At what time of the year do the leaves fall off the trees? Turn the hands of this clock so that it shows 4 o'clock. Who took the shortest time to...? Starting at 12, which number is halfway around the clock face? Sam's school starts at 9 o'clock. Sam went to the dentist and got to school half an hour late. Draw the time Sam got to school on the clock. Level 2 Imagine a clock with hands on the wall in front of you. The long hand is pointing to the 6. The small hand is pointing between 8 and 9. What time is it? I can read the numbered divisions on a scale, and interpret the divisions between them (2) Look at this metre ruler. What length does this mark between 10cm and 20cm show? Is the water in this measuring jug nearer 1, 2 litre or 1 litre? On the graph, how do you work out the numbers between the labels? Which way of getting to school was used by 7 children? These labels show only 0, 2, 4, 6, 8 and 10. How could you find 7? If this scale carried on, what other numbers do you think would be shown? Would the number 34 be shown? How can you tell? This metre stick has a number label every 5 cm. Where is the mark for 17 cm? Point to 65cm on a metre stick marked in centimetres and numbered in tens.] What measurement is this? [Point to half a litre on a 1 litre measuring jug.] What measurement is this? How do you work out the numbers between the ones that are shown on the scale? If this scale continued, what other numbers would be marked? How heavy is Peter?

3 Some children rolled toy cars down a slope. How far did the blue car roll? How much further did the green car roll than the red car? Estimate how far the yellow car rolled. Look at the number line. The arrow points to 50. Draw an arrow to show where the number 125 belongs. This scale shows the weight of a letter. How much does the letter weigh? I can use a ruler to draw and measure lines to the nearest centimetre (2) Tell me some important tips to help someone to measure a length using a tape or ruler accurately. What would happen if you didn't start measuring from zero on the ruler? Here is a ruler [marked in centimetres] and here are some lines [measuring for example 8 cm, 15 cm]. Tell me how you would measure the lines using the ruler.

4 I can use units of time (secs, mins, hrs, days) and know the relationships between them I can read the time to the quarter hour; identify time intervals, including those that cross the hour (2) What takes about 10 seconds? 1 minute? 1 hour? Look at these pictures of different events. [Point to a picture.] How long would this activity take? Use this seconds timer. Time me while I walk across the room and back again. How long did I take? How many minutes are there in 1 hour? It is half past 4. How many minutes have passed since 4 o'clock? What is the time on this clock? What time was it 2 hours ago? Level 3 How many minutes are there in one hour? Reading takes 20 minutes, and playing takes 40 minutes. Think of some more pairs of activities to make up one hour. Turn the hands of this clock so that it shows a quarter past 4. What time will it show in half an hour's time? Who took the shortest time to...? Anya went into the library at a quarter to eleven and came out at a quarter past twelve. How long was she in the library? Jane left home at ten fifteen. It took her half an hour to get to the seaside. At what time did Jane get to the seaside? The bus left at 9 o'clock to go to the zoo. It arrived 1 hour and 15 minutes later.

Bethany says she sleeps for 19 hours every night. Can that be right? How do we know? How do you use a clock face to help you to work out how many minutes there are between a quarter past 2 and a quarter to 3? Two clocks show the same time. Which are they? I went for a walk at 4 o'clock. My walk took me 45 minutes. Draw on these clocks what time it was when I ended my walk.

5 I can read the time on a 12-hour digital clock and to the nearest 5 minutes on an analogue clock; calculate time intervals and find start or end times for a given time interval (3) How would this time appear on a 12-hour digital clock? Kevin leaves home at quarter past 8 and arrives in school at 20 to 9. How long is his journey? How did you work this out? Ben's clock says 7:50 when he gets up. Place the hands on this clock to show this time. How long is it between the times shown on these two clocks? Show me how you worked this out. How would a digital clock show the time twenty minutes to six? The car journey to work takes Rob 20 minutes. He needs to be at work at 9 O'Clock. Move the hands on this clock face to show the time that he should leave. I can read, to the nearest division and halfdivision, scales that are numbered or partially numbered (3) Show me where 24 What length is shown below? cm would go on this tape measure/ruler. What temperature does this thermometer show? Choose a set of scales to weigh how heavy your shoe is to the nearest 100 g. Draw a line that is 2 cm longer than this one [a line 5 cm long]. What measurement is shown on the scale?

6 What measurement is shown on these scales? (Circular scale , 100s marked on, arrow points to 350) Explain how you worked this out. What is each division on this scale worth? How did you work this out? How could you check that you are right? Draw where the dial would go for a weight of 45 g. How do you know? What is each division on this measuring jug worth? How did you work this out? How much water is in the jug? I can use the information to measure and draw to a suitable degree of accuracy (3) (no specific examples of AfL questions are given for this in the Renewed Framework)
