The document discusses strategies for writing related multiplication and division number sentences using fact families. It provides examples of writing related sentences from given number equations and solving word problems using related multiplication and division sentences. Students are asked to write related sentences for given number equations and solve for variables in equations.

1. the Z strategy Relating Multiplication with Division

5. Now, was that so hard?

11. Jacob solved the following multiplication equation: 23 x 8 = 184 What number sentence could he use to check his answer?

12. 23 x 8 = 184 184 ÷ 8 = 23 or 184 ÷ 23 = 8

14. Gabrielle solved the following math problem: 32 x 4 = 128 What number sentence could she use to check her answer?

15. 128 ÷ 4 = 32 32 x 4 = 128

17. the Z strategy continued…

22. If 48 ÷ n = 6 What does 6 x n = ?

24. True or False The following statement is correct: If n x 3 = 18, then n = 18 ÷ 3

25. True because… If n x 3 = 18, then n = 18 ÷ 3 n = 6 6 x 3 = 18 6 = 18 ÷ 3 ZZZZ N x 3 = 18

26. True or False The following statement is correct: If 5 x f = 35, then 35 = 5 ÷ f

27. False because… If 5 x f = 35, then f = 7 And 35 = 5 ÷ 7? NO WAY! ZZZZZZ 5 x f = 35

28. Focused and alert, no sleeping now!

32. Which statement is correct? A. If a ÷ 3 = 7, then a = 7 x 4 B. If 5 x 6 = b , then 6 x b = 5 C. If 14 ÷ y = 2, then y = 14 x 2 D. If d = 24 ÷ 6, then d x 6 = 24 D 500
