Worksheet: Subtracting Ones from Two-Digit Numbers with Regrouping

In this worksheet, we will practice subtracting a one-digit number from a two-digit number when crossing a ten and modeling this with place value equipment.

Q1:

Chloe used place value blocks to show that 73 is 7 tens and 3 ones.

She wants to take away 9 from 73, but there are not enough ones.

Pick another way she could make 73 so she can take away 9 ones.

  • A
  • B
  • C
  • D

Take away 9 ones to find 739.

Q2:

A car park has 41 spaces. Two spaces are taken. How many are left?

Q3:

Mason used place value blocks to show 64 in 6 tens and 4 ones.

He wants to take away 6 from 64. But there are not enough ones.

Pick another way he could make 64 so he can take away 6 ones.

  • A
  • B
  • C
  • D

Take away 6 ones to find 646.

Q4:

Jacob has 23 marbles. He decides to give his friend Liam 6 marbles. How many marbles does Jacob have left?

Q5:

Subtract 8 from 66.

Q6:

Noah wants to calculate 527. He writes 52 as 4 tens and 12 ones to be able to subtract 7 from it.

Take away 7 ones. What is 527?

Q7:

Jacob is subtracting 8 from 72. He drew this to show 72 as 7 tens and 2 ones.

Find the answer to 728 by subtracting 8 ones.

Q8:

Mia showed the number 64 using place value blocks. 64 is 6 tens and 4 ones.

She wants to subtract 7 ones. 64 is also 5 tens and 14 ones.

Use her model to find 647.

Q9:

Mia is calculating 334. She showed 33 using place value blocks.

After she regroups and subtracts 4, how many tens and ones will be left?

  • A3 tens and 4 ones
  • B2 tens and 4 ones
  • C3 tens and 7 ones
  • D2 tens and 9 ones

Q10:

Find 6142.

Q11:

Find 557.

Q12:

Olivia collected 31 shells from the beach yesterday. She gave 7 of them to her friend. How many shells does she have left?

Q13:

Look at how Mason solved a subtraction question.

Which question was he working on?

  • A185
  • B186
  • C816
  • D815

Pick one way to write down the calculation he did.

  • A
  • B
  • C
  • D

What is the answer?

Q14:

We can think about place value to help us subtract.

Pick the correct way to decompose 53 into tens and ones.

  • A
  • B

Subtract 7 from 53 by following these steps:

  • Regroup 1 ten into 10 ones.
