2nd Grade Addition and Subtraction Worksheets
In second grade, children are expected to add and subtract within 20 quickly and without counting, then use that speed to solve two-digit problems within 100. These worksheets follow that path in three steps: facts, then missing numbers, then bigger numbers with regrouping.

Tips for parents
- How to help: teach "make a ten" (8 + 5 = 8 + 2 + 3) before regrouping. A child who can split numbers into tens and ones understands regrouping instead of memorising steps.
Frequently asked questions
What is regrouping?
When the ones add up to 10 or more, ten ones become one ten. In 27 + 15, 7 + 5 = 12, so you write 2 and carry 1 ten.
Should my child still use fingers in 2nd grade?
It is normal early in the year. These pages move children toward strategies like doubles and making ten, which replace finger counting.
