12 Unit 4 Review (continued) 3) Daryl is playing What s My Polygon Rule?. He places his polygons this way: Fits the Rule *ANSWER KEY* Does Not Fit the Rule A C B a. Draw a different shape that fits the rule. Possible answer: b. What could Daryl s rule be? Explain how you know. Possible answer: Daryl s rule could be shapes with two pairs of parallel sides because A and B both have two sets of parallel lines and C only has 1 pair of parallel sides. 4) Look at these shapes. D E a. How are they alike? Possible answer: They have two pairs of parallel sides. They both have 4 sides and 4 angles. b. How are they different? Possible answer: Shape D has 4 right angles, but Shape E does not have any right angles.

13 Unit 4 Review (continued) 5) Trace the boundary of this shape. Then find the perimeter. Remember to write the units. *ANSWER KEY* 3 feet 18 feet Perimeter: (unit) 3 feet b. Explain how you figured out the perimeter. c. Which name(s) could be used to name the shape in 5a? Mark the box next to all that apply. Possible answers: I multiplied the length of each side, 3 feet, by the number of sides, 6 sides. 6 multiplied by 3 is 18. I added and got a total of 18 feet. polygon hexagon pentagon quadrangle 6) Find the perimeter and area of this rectangle. Key: = 1 square centimeter a. Perimeter = centimeters b.

16 *ANSWER KEY* Name: Date: EVERYDAY MATHEMATICS 3 rd Grade Unit 4 Challenge Review 1) Isabella measured this line segment in inches and it says about 6 inches long. Olivia measured the line segment in ½ inches and says it is about 12 ½-inches long. Do you agree with Isabella and Olivia? Explain your answer. _ Possible answers: Yes, I agree with Isabella and Olivia because _ both 6 inches and 12 ½-inches are the same length. Two ½- _ inches makes 1 whole inch. 2) What is the smallest number of sides a polygon can have? Draw an example of a polygon with this many sides. Possible answers: 3 sides Why are there no polygons with fewer sides? Possible answers: If you try to make a polygon with 2 sides, it will _ not be closed. It would look like an L or V, and there wouldn t be another side to connect it.

17 Unit 4 Challenge Review (continued) *ANSWER KEY* 3) David s partner drew this card and a Partner s Choice card in The Area and Perimeter Game: 3 8 Should David have his partner record the area or the perimeter? Explain. Possible answer: The perimeter is 22 units and the area is 24 square units, so I would choose the perimeter because it is the smaller measure.

18 *ANSWER KEY* Name: Date: EVERYDAY MATHEMATICS 3 rd Grade Unit 4 Cumulative Review 1) Write a multiplication number sentence for this array Number sentence: 2) Draw an array to match this number sentence. 5 4 = = 21 or 7 3 = ) Fill in the blanks. 4 a. 3 = 12 5 b. 25 = 5 3 c. 10 = 30 4) Carlos was solving this problem: 30 5 = 6. He asked himself, 5 times what number is 30? Then he knew the answer. How did Carlos figure out the answer? Possible answers: Carlos used 5 6 = 30 to solve 30 5 = 6 since both facts are in the same fact family.

19 Unit 4 Cumulative Review (continued) 5) Complete. *ANSWER KEY* Rule 3 in out ) Round each number to the nearest 10 and nearest 100. a. Round to the nearest 10. b. Round to the nearest c. Explain how you rounded 381 to the nearest 100. Possible answer: I made an open number line. 381 is between 300 and 400. I marked 350, and then thought about where 381 should be. It is more than 350, so 381 is closer to 400 than 300.

20 *ANSWER KEY* Unit 4 Cumulative Review (continued) 7) Jesse went for a walk at 2:15 P.M. He walked until 2:50 P.M. How many minutes did he walk? Show your work. You may use your toolkit clock or draw an open number line. Jesse walked for (unit) 8) Use the information in the bar graph to answer the questions below minutes Favorite Ice Cream Flavor Number of Children vanilla chocolate strawberry mint chocolate chip Flavors other a. How many children voted in all? b. How many more children chose chocolate than vanilla? c. How many more children voted for strawberry and mint chocolate chip than 20 children vanilla? d. How did you solve 8c? Explain. 155 children 10 children Possible answer: I added the number of children who voted for strawberry and mint chocolate chip and got 55. I know that 35 children voted for vanilla, so I subtracted 35 from 55 and got 20.
