Addition Worksheets

Addition is the very first arithmetic operation children learn, and building strong addition skills creates the foundation for all future math. From combining small groups in Kindergarten to multi-digit addition with regrouping in Grade 4, our free addition worksheets cover every step of the journey.

Kindergarten and Grade 1 worksheets focus on sums to 10 and 20 using concrete strategies like counting on, making ten, and using number lines. In Grades 2-3, students progress to two-digit and three-digit addition with regrouping, developing both the standard algorithm and mental math flexibility. By Grade 4, students confidently add numbers to 10,000 and begin adding decimals.

All worksheets are curriculum-aligned, ensuring your child practises grade-appropriate skills. Each problem can be solved on screen with instant AI grading or printed for pencil-and-paper practice. Choose a grade below to get started.
