1 Explorations Exploring Length, Area, and Attributes Objectives To guide children as they measure lengths and distances to the nearest inch and centimeter, explore area by tiling surfaces, and sort attribute blocks according to rules. epresentations etoolkit Algorithms Practice EM Facts Workshop Game Family Letters Assessment Management Common Core State Standards Curriculum Focal Points Interactive Teacher s Lesson Guide Teaching the Lesson Ongoing Learning & Practice Key Concepts and Skills Distinguish between centimeter and inch. [Measurement and Reference Frames Goal 1] Compare lengths in centimeters and. [Measurement and Reference Frames Goal 1] Measure to the nearest in. and cm. [Measurement and Reference Frames Goal 1] Find area by tiling with pattern blocks and counting shapes. [Measurement and Reference Frames Goal ] Use rules to sort attribute blocks.

For a mathematics and literacy connection, obtain copies of A Cloak for the Dreamer by Aileen Friedman (Scholastic Inc., 1995) and Inch by Inch by Leo Lionni (HarperCollins Publishers, 1995). Teacher s Reference Manual, Grades 1 3 pp , 14 8 Unit 4 Addition and Subtraction

4 Exploration F: Sorting Attribute Blocks (Math Journal 1, p. 103; Math Masters, pp ) Algebraic Thinking Children sort attribute blocks with these steps: 1. Cut apart the cards on Math Masters, page 109. PROBLEM SOLVING. Shuffle the cards and put them in a pile facedown. SMALL-GROUP 3. Label one sheet of paper These Fit the Rule. Label a second sheet These Do Not Fit the Rule. 4. Children take turns being the Rule Maker. The Rule Maker draws a card from the shuffled pile and puts it out for all to see. 5. The other children take turns putting blocks on the appropriate sheets labeled These Fit the Rule and These Do Not Fit the Rule. Children record one of their rules on journal page 103 and describe those attribute blocks that fit the rule and those that don t. Materials Tiling Surfaces with Shapes square pattern blocks slates sheets of paper Pattern-Block Template scissors Everything Math Deck cards, if available 1. Use square pattern blocks. Tile a card by covering it with the square pattern blocks. Lay the blocks flat on the card. Don t leave any spaces between blocks. Keep the blocks inside the edges of the card. There may be open spaces along the edges. Count the blocks on the card. If a space could be covered by more than half of a block, count the space as one block. Do not count spaces that could be covered by less than half of a block. Number of square pattern blocks needed to tile the card: EM3cuGMJ1_U04_80_111.indd 101 Answers vary. Trace the card. Use your Pattern-Block Template to draw the square pattern blocks you used to tile the card. Math Journal 1, p /0/10 5:16 PM Adjusting the Activity Encourage children to work in partnerships when taking turns putting blocks on the appropriate sheet. In this way, children are able to discuss their choices. Alternately, the whole group can work together as a team to decide which blocks fit the rule and which do not. Have children make up their own rules and write them on the two blank cards on Math Masters, page 109. A U D I T O R Y K I N E S T H E T I C T A C T I L E V I S U A L NOTE The Attribute Rule Cards from Math Masters, page 109 will be needed again in Lesson 5-1. Collect the cards and store them in envelopes. Name Attribute Rule Cards Tiling Surfaces with Shapes continued. Use Everything Math Deck cards to tile both a slate and a Pattern-Block Template. How many cards were needed to tile them? Slate: cards Answers vary. Pattern-Block Template: cards Answers vary. 3. Fold a sheet of paper into fourths. Cut the fourths apart. Use them to tile larger surfaces, such as a desktop. Surface Number of Fourths Answers vary. small blue shapes large red shapes large shapes, but not triangles circles, but not red Follow-Up With a partner, find things in the classroom that are tiled or covered with patterns. Make a list. Be ready to share your findings. blue and yellow shapes, but not circles red and yellow small shapes not triangles or squares large triangles, but not yellow Math Masters, page 109 Math Journal 1, p. 10 Lesson 85

5 An Attribute Rule Choose an Attribute Rule Card. Copy the rule below. Rule: Draw or describe all the attribute blocks that fit the rule. Draw or describe all the attribute blocks that do not fit the rule. These blocks fit the rule: Rules, drawings, and descriptions vary. Ongoing Learning & Practice Playing Beat the Calculator (Math Journal 1, p. 4; My Reference Book, pp. 14 and 15) PARTNER These blocks do not fit the rule: See My Reference Book, pages 14 and 15 for directions. Children play Beat the Calculator to develop their recall of addition facts. Using the Facts Power Table on journal page 4, children should record the facts for which they can beat the calculator by making a check mark in the box containing that fact. Whenever they receive three check marks for a particular fact, they can write the sum in that box to indicate they know the fact from memory. The Caller should select problems at random from the white area of the Fact Power Table. Math Journal 1, p. 103 EM3cuGMJ1_U04_80_111.indd 103 1//10 1:01 PM Ongoing Assessment: Recognizing Student Achievement Exit Slip Use an Exit Slip (Math Masters, page 415) to have children record facts from boxes in which they have at least one check mark. Children are making adequate progress if they have recorded at least half of the facts from the unshaded area. Some children will have recorded other facts. [Operations and Computation Goal 1] Math Boxes (Math Journal 1, p. 104) INDEPENDENT Name Teaching Master What s My Attribute? Work with a small group. Materials Math Journal 1, p. 103 Attribute Rule Cards (Math Masters, p. 109) scissors sheets of paper 1 set of attribute blocks: triangles, circles, squares (large and small; red, yellow, and blue) red, yellow, and blue crayons Directions 1. Cut apart the Attribute Rule Cards on Math Masters, page Mix the cards. Stack them facedown. 3. Label one sheet of paper These Fit the Rule. 4. Label another sheet These Do Not Fit the Rule. 5. Take turns being the Rule Maker. 6. The Rule Maker takes the top card from the stack. 7. The Rule Maker puts the card faceup for everyone to see. 8. Group members take turns choosing a block. Mixed Practice Math Boxes in this lesson are linked with Math Boxes in Lesson 4-5 and Lesson 4-9. The skill in Problem 6 previews Unit 5 content. Writing/Reasoning Have children draw, write, or verbalize their answers to the following: For Problem 3, explain how you know a number is even or odd. Sample answer: A number is even if it ends in, 4, 6, 8, or 0. A number is odd if it ends in 1, 3, 5, 7, or 9. Home Link (Math Masters, p. 110) INDEPENDENT Home Connection Children measure sections of a path to the nearest inch. Then they combine their measurements to find the total length of the path.
