B. How con you subtract 176 from 318?
THINK: Do I need to regroup?
Show the subtraction in your visual model. Remember to show any regrouping.
Answer:
We have to regroup in tens place as we cannot subtract 7 from 1
1 becomes 11 after regrouping
11 – 7 = 4

C. Solve the problem.
___________ bats stay in the cave.
Answer:
142 bats stay in the cave.
Explanation:
We have to regroup in tens place as we cannot subtract 7 from 1
1 becomes 11 after regrouping
11 – 7 = 4
Hundreds are regrouped tens so, 3 hundreds become 2 hundred
2 – 1 = 1

Turn and Talk How is 1 hundred regrouped as 10 tens?
Answer:
HMH Into Math Grade 2 Module 17 img 4
