Ms. Santos’s Apples Solve the following problems in your math notebook: As you work on these problems, think about the relationship between them. How are these two problems the same? How are they different? What do the arrays or pictures that you draw for each problem show you about the relationship? After 10 mins.: Share and record representations of the problems on chart paper.

14 Possible Solutions: 168 ÷ 28= 6168 ÷ 14=12 14 Ms. Santos’s Apples When Ms. Santos found that she could put only 14 apples in a box, how did that change the number of boxes she needed? What do you know about the numbers 28 and 14? What do you notice about your solutions to these two problems? 6 x 28=16812 x 14=168 28 14 6 28 14 66

Possible Solutions: 168 ÷ 28= 6168 ÷ 14=12 14 Ms. Santos’s Apples How does solution 1 show what happens to the number of boxes? How does solution 2 show what happens when the size of the boxes is cut in half? Would this ides work with other numbers? What if we wanted to pack 168 apples in even smaller boxes that hold only 7 apples? What do you think would happen to the number of boxes? 6 x 28=16812 x 14=168 28 14 6 28 14 66 1. 2.

Independent Work: Related Problems about Doubles and Halves Complete Student Activity Pages 53 and 54 Problems 1a-f: Solve the problem in each pair, and then use that answer to help solve the second problem. As you look at the two problems, notice whether one factor in the second problem has been doubled or halved. Look carefully at each pair because the second problem does not always change in the same way. Think of each problem pair in the story context of apples in boxes. Math Menu: Once your paper is complete: Play Multiplication Migration in groups no larger than 4.
