Question 27. a. Student gives correct answers: There are 6 seedlings in each row. b. Student gives correct answer: The fact family is: 8 × 6 = 48 6 × 8 = 48 48 ÷ 6 = 8 48 ÷ 8 = 6 c. Student gives accurate explanation: Sample explanation: The fact family helps me to understand what is happening in the problem. I don’t know 48 ÷ 8 as easily as I know 6 × 8 = 48. Understanding the relationship between multiplication and division helps me solve the problem. 3.OA.6 28. a. Student gives correct answer: 20 ÷ 5 = ? b. Student gives correct answer and shows work: There are 4 boxes of markers per table. c. Student gives accurate explanation: This type of question relates to division as sharing because Ryan is passing out markers to each of the 4 tables until there are not any more to pass out. 3.OA.2 Copyright © Swun Math Grade 3 Unit 3 Assessment (Answer Key) Page 2
