Addition with regrouping worksheets
Each print is a different sheet with its own answer key. You don't need to sign up.
Add the ones first. When they make ten or more, write the ones digit and carry the ten to the next column.
Three grades, each its own sheet. Print one here, or open a grade for examples and teaching notes.
Print by grade
-
2nd grade Core grade
Each print is a different sheet with its own answer key. You don't need to sign up.
Every problem on these sheets needs a carry. Second graders add two two-digit numbers, get ten or more in the ones column, write the ones digit and move the ten over. The stacked layout keeps the columns straight while the habit forms.
-
3rd grade
Third graders add three-digit numbers where the ones, the tens, or both make ten or more. Every problem regroups at least once, so your child practises carrying into the tens and the hundreds instead of hoping the columns stay small.
-
4th grade
Fourth graders add four-digit numbers with a carry in at least one column, and often two or three. The point is fluency with the standard algorithm on numbers big enough that place value has to be tracked, not guessed.
