Addition within 100
Free worksheets for Grade 2. 20 problems per page, a new sheet at every click, with an answer key.
Sheets are A4. On US Letter paper, choose "Fit to page" (or "Scale to fit") in your print settings. Free, with no sign-up.
Addition within 100 worksheets are made automatically from the choices you make: the operation and the kind of problem. Every click on "New sheet" gives different problems (20 on a page), so you can practice daily without repeating a sheet.
Within 100, Grade 2 children work with two-digit numbers. The sheets avoid trivial problems such as 3 − 2 and mix problems with and without regrouping (carrying and borrowing). Think in tens and ones: 47 + 26 is 40 + 20 and 7 + 6.
Tip for parents: one sheet a day, about ten minutes. If the sheet feels too hard, go back to a smaller range. If it feels too easy, choose missing-number or vertical problems.
Frequently asked questions
Which grade are the addition within 100 sheets for?
They are designed for Grade 2, but any child practicing within 100 can use them.
What is the "missing number" type?
One of the numbers is missing instead of the answer, for example 4 + ___ = 9. It builds the link between addition and subtraction.
Is there an answer key?
Yes. Tick "Add an answer key" and every sheet is followed by a page with the answers in color.
