Practicing Addition With Regrouping (Carrying)
Addition with regrouping worksheets train students to carry ten ones into the tens column, or ten tens into the hundreds column, whenever a place-value column sums to 10 or more. Mastering regrouping is essential for understanding how our base-ten number system bundles groups of ten across adjacent places.
Guaranteed Carrying Practice
Every problem generated on this page is mathematically verified to require regrouping in at least one place-value column. Adjust the digit count, minimum and maximum addend values, and column layout to match your students' grade level.
Common Student Mistakes & How to Fix Them
- Writing both digits of a two-digit column sum in the answer row: Remind students that only the ones digit of the partial sum stays in the current column while the tens digit is carried above the next column to the left.
- Forgetting to add the carried digit: Encourage learners to circle or check off the carried
1at the top of the column as soon as they include it in the next column's sum. - Adding from left to right: Always start in the ones place so any regrouped ten is carried into the tens column before that column is totaled.

Classroom Printing & Assessment Tips
Enable the Carry Boxes or vertical column layout so students have dedicated space above the tens and hundreds columns to record regrouped digits. Teachers can print a single problem set for the whole class using a shared seed number, or generate multiple distinct versions with matching answer keys for small-group stations and homework packets.
