Addition without regrouping worksheets

In addition without regrouping, each column totals less than ten. For 23 + 14, the ones give 3 + 4 = 7 and the tens give 2 + 1 = 3, making 37.

Try an example

Addition combines quantities or adds one quantity to another. For 8 + 5, make 10 first: split 5 into 2 and 3, calculate 8 + 2 = 10, then add the remaining 3 to get 13. Draw the groups as dots if you still need to see them.

What to check

Check that you counted every item once. In column addition, align ones with ones and tens with tens. Practice without regrouping before adding the step of exchanging ten ones for one ten.

Explain and check

Work through one example aloud before independent practice. To check 18 + 7 = 25, calculate 25 − 7. If a word problem asks about meters or coins, include that unit and check whether the answer fits the situation.
