2 Digit Subtraction Worksheets With Regrouping
Show your student that regrouping changes how a number is represented, not its value.
Teaching notes for parents and teachers
How to teach it
Use base-ten blocks to exchange one ten for ten ones. Record both changes before subtracting.
Example to work through together
Use the model below as you explain the example. Have your student point to the quantities as you discuss them.
Ask your student
Do we still have the same starting amount after the exchange?
If your student needs help
If the student adds ten ones without reducing the tens, compare the blocks with the written number.
Make a practice set
Select the worksheet, answer key, or both. When both are selected, the answer key prints after the questions. Keep it separate if you want your student to work independently.
After your student finishes
Ask the child to explain what changed and what stayed the same when a ten was exchanged. Check the ones subtraction and the remaining tens separately. An answer of 34 for 42 − 18 can mean that the child used the original four tens after trading one away. Revisit the drawing before assigning another set.
