Addition worksheets for Grade 2

Grade 2 is where addition grows up. Kids finish off facts to 20, then start adding two-digit numbers. The big new idea is regrouping, sometimes called carrying, when ones add up to ten or more and a ten moves to the next column.

If facts to 20 still feel shaky, begin with sums to 20. The easy level avoids crossing ten, and the hard level makes every problem cross it and uses stacked layout. Once that feels steady, move to sums to 100. Easy adds a one-digit number to a two-digit number with no regrouping. Medium adds two two-digit numbers, still without regrouping. Hard needs regrouping, so save it for last.

Three addends help kids spot friendly pairs, like 6 + 4 hiding inside 6 + 3 + 4. Doubles are quick wins that also help with near doubles, such as 7 + 8. Missing addend sheets, like 35 + __ = 60, prepare your kid for subtraction without saying so.

The most common slip is forgetting to add the carried ten. Ask your kid to write the small 1 above the tens column, and to line up the digits neatly. Two or three hard problems a day is plenty.
