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.


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.


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


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.


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


Subtract 8 from 66.


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?


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.


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.


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


Find 6142.


Find 557.


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


Look at how Mason solved a subtraction question.

  • D815

Pick one way to write down the calculation he did.

  • A
  • B
  • C
  • D

What is the answer?


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:
