Practice all of addition
This mixed review draws from addition facts, two- and three-digit addition and mental strategies in one set — the fastest way to see what’s solid.
How to learn addition, in order
Addition grows from instant recall of the facts. Start with Addition Facts until sums within 20 are automatic — this is the single most important step, because every later method leans on it. Then move to 2-Digit and 3-Digit Addition to learn regrouping (carrying), and on to Multi-Digit Addition with larger numbers and column sums. Mental Addition can be practised alongside any of these to build speed.
Addition by grade
- Grades K–1: the meaning of adding, and facts within 10 then 20.
- Grade 2: two-digit addition with regrouping, and mental strategies.
- Grades 3–4: three- and four-digit column addition.
Common mistakes, and how to help
The classic errors are forgetting to carry (writing the carried digit above the next column and crossing it off once used prevents this) and misaligning place value when numbers have different lengths — lining the ones up on the right, on grid paper, fixes most of it. If facts are still being counted on fingers, that’s the place to spend a few minutes a day before anything else.

Frequently asked questions
Is the addition practice free?
Yes — all practice and printable worksheets are free, with no account needed and no ads inside the practice.
What order should addition be learned in?
Facts within 20 first, then 2-digit with regrouping, then 3-digit and multi-digit. Mental strategies build alongside.
What grade is addition with regrouping?
Two-digit regrouping is grade 2; three-digit comes in grades 2–3 and larger multi-digit in grade 4.
How do I help my child memorise addition facts?
Short daily sessions and the make-a-ten strategy. The picture groups on the facts page let a child count and see each sum.
What is the make-a-ten strategy?
Breaking a number to complete a ten first — for 8 + 5, take 2 from the 5 to make 10, then add the remaining 3 to get 13.
Can I print addition worksheets?
Yes — each skill page has a “Print a worksheet” button that makes a fresh 20-question sheet with an answer key.
