## HMH Into Math Grade 4 Module 7 Lesson 1 Answer Key Represent Division with Regrouping

I Can represent and record division problems with a 1-digit divisor and regrouping.

Dani manages a charter boat business. She has these fishing lures for 3 boats. She wants to put the same number of lures on each boat. How many lures should Dani put on each boat? Dani manages a charter boat business.

She has these fishing lures for 3 boats.

She wants to put the same number of lures on each boat.

Total lures = 4 x 10 + 8 = 48

So, 48 ÷ 3 = Dani put 16 lures equally on each boat. Turn and Talk Why does Dani need to open one package of lures in order to divide all the lures equally?

In order to get equal lures for each boat, she has to open one package of lures. Because 4 packets i.e., 4 x 10 = 40 can not be shared equally, one lure will be remained after sharing 39, 39 = 3 x 13. So, she has to open one package of lures in order to divide all the lures equally.

1. Frank owns a charter boat business. He buys 56 fishing rods. Frank divides the rods equally among his 4 boats. How many fishing rods does each boat get? Find 56 ÷ 4.
Use base-ten blocks to show 56 as 5 tens 6 ones.
Try to put all the blocks into 4 equal groups.
Draw a quick picture to show your work. A. Which blocks are not in a group? Why?
___________________________
B. How can you regroup the leftover ten with the leftover ones?
___________________________
C. Use your blocks to show the regrouping. Then finish putting all the blocks in 4 equal groups.

• How many tens and ones are in each group? ___________
• How many fishing rods does each boat get? _________

Turn and Talk How can regrouping 1 ten as 10 ones help when you divide?

Step It Out

2. Use quick pictures to represent division,
Find 85 ÷ 3. The picture shows 85 as 8 tens 5 ones. The 3 circles represent the equal groups. Cross off tens and ones as you put them into the groups.
A. Share the 8 tens equally among the 3 groups. How many tens are in each group? ___
How many tens are left over? _______ B. Regroup the leftover tens as ones.
How many ones are there now? ________
C. Share the ones equally among the 3 groups.
How many ones are in each group? ________
How many ones are left over? ________
