About the Kindergarten Math Worksheets

Kindergarten math is all about numbers to 10, so this page opens on addition within 10: two numbers from 0 to 10 whose sum is 10 or less. Choose 12 problems for a page with lots of space, which suits students still learning to write their numbers, or 16 to 24 as they get faster. Switch the operation to Subtraction for take-away facts within 10, where the answer is never below zero, or to Mixed for a page with both. Every PDF comes with an answer key on page 2, and you can turn off the Name & Date lines if students don’t write their names yet.

Ways to use kindergarten math worksheets

  • Count it out

    Give students counters or the Ten Frame in Math Manipulatives and let them build each problem before writing the answer.

  • Math center

    Keep a stack of 12-problem pages at a center and print a new one with New problems each week.

  • Together on the board

    Solve the page together in Classroom Presentation Mode, with a student coming up for each problem.

  • Take-home practice

    Send a page home with the answer key so families can check the work.

Frequently Asked Questions

Do the problems use zero?

Yes. Within 10, numbers start at 0, so students also practice adding and taking away zero.

Can I mix addition and subtraction?

Yes. Choose Mixed with Within 10 for a page of both, with no multiplication or division.
