Question 1.

Serena has 52¢. Then she pays 35¢ for a snack. How much money does she have now?

A. How can you use tools to show 52? Draw to show what you did.

Answer:

Given that,

Serena has money = 52 cents.

Serena pays for snack = 35 cents.

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.

The minuend is 2 and subtrahend is 5.

We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

B. If there are not enough ones to subtract 5, regroup I ten as 10 ones. How can you show the regrouping in your drawing above?

Answer:

52 – 35 = 17

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.

The minuend is 2 and subtrahend is 5.

We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

C. How can you subtract the ones? Show your work in your drawing above. Write the number of ones left in the ones place.

Answer:

After regrouping in the one’s place, the numbers are 12 and 5, 12 – 5 = 7.

The number of ones in the one place is 7.

D. How can you subtract the tens? Show your work in your drawing. Write the number of tens left in the tens place.

Answer:

After regrouping in the tens place, the numbers are 4 and 3, 4 – 3 = 1.

The number of tens in the tens place is 1.

E. Solve the problem. _________ ¢

Answer:

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.

The minuend is 1 and subtrahend is 8.

We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

B. How can you subtract the ones? Regroup if you need to. Show your work in the chart.

Answer:

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.

The minuend is 1 and subtrahend is 8.

We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

In the ones place 11 – 8 = 3

C. How can you subtract the tens? Show your work in the chart.

Answer:

41 – 28 = 13

Here we use regrouping in subtraction. Because the minuend is smaller than the subtrahend.

The minuend is 1 and subtrahend is 8.

We can regroup by borrowing 1 ten from the tens place to one place to make ten ones.

In the tens place 3 -2 = 1

D. What is the difference?

Answer:

41 – 28 = 13

The difference is 13.

**Turn and Talk** How do you know when you need to regroup a ten to subtract ones?

Answer:
