# 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 .

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 .

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 . He writes 52 as 4 tens and 12 ones to be able to subtract 7 from it. Take away 7 ones. What is ?

Q7:

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

Q9:

Mia is calculating . 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
