MathSheetGo · Sheet #1451Please review before classroom use

Every problem on this page requires regrouping in the ones column. The top ones digit is smaller than the bottom ones digit, so students must exchange one ten for ten ones before subtracting. The larger 2-digit number stays on top and all answers are zero or more.

Because every example contains the target step, the sheet is useful for concentrated practice immediately after borrowing is introduced. It also makes errors easier to diagnose than a mixed sheet where only a few questions require regrouping.

When to use it

Use this sheet once students can subtract 2-digit numbers without regrouping and can explain that one ten equals ten ones. It works for guided practice, a small-group reteaching session, homework after a borrowing lesson or a short assessment before moving to three digits.

Teaching tips

  • Model the exchange with base-ten blocks before writing crossed-out digits on paper.
  • Use consistent language: trade one ten for ten ones, reduce the tens digit by one, then add ten to the ones digit.
  • Have students mark the regrouped digits before doing either subtraction step.
  • Check each result with addition to connect subtraction back to a familiar inverse operation.
  • If students subtract the smaller ones digit from the larger one without borrowing, return to a concrete example such as 32 − 18.

How to print this worksheet

  1. Check the settings above. They are already set for 2-digit subtraction with regrouping.
  2. Pick 10, 15, 20 or 30 problems, a title, and the name or date lines you want.
  3. Choose US Letter or A4 to match the paper in your printer.
  4. Press Download PDF for a file you can save and reuse, or Print to send it straight to your printer.
  5. Keep the answer key page for yourself. The sheet number in the footer lets you make the exact same sheet again later.

What comes next

Change Borrowing to Mixed after the procedure is secure so students have to decide when regrouping is necessary. Then move to 3-digit subtraction with borrowing, where a trade may be needed in the ones, tens or both columns.

Frequently asked questions

Does every problem require regrouping?
Yes. The top ones digit is smaller than the bottom ones digit in every generated problem, so one ten must be regrouped as ten ones.
Are regrouping and borrowing the same thing?
Yes. Regrouping is the more precise place-value term, while borrowing is the traditional classroom name for the same procedure.
Are answers included?
Yes. Leave Answer key page selected to include a separate key when you print or download the PDF.
