Addition with regrouping worksheets
Regrouping — carrying a ten to the next column — is the first genuinely mechanical skill in arithmetic, and the place where many children wobble. Every problem on these free printable sheets requires a carry, so no practice minute is wasted on easy sums.
If they get stuck
Ready for harder? The smudged sum — the total is given and two of the digits are not.
Addition with regrouping
The answer key prints on a separate page.
What's on this sheet
Most mixed worksheets only include a few regrouping problems per page, which means a child who struggles with carrying gets three chances to practice it and seventeen problems they already know. These sheets flip that: every sum on the page is one where the ones column overflows.
Why this sheet works
Sheets are available in horizontal or stacked (column) format. The stacked format mirrors how regrouping is taught in class, with the two addends aligned by place value and space above for the carried digit. Start stacked while the skill is new, then move to horizontal to build mental math.
How this one works
One question from a sheet like this one, worked a step at a time — with a sentence saying what just happened and why.
