How to practise addition facts
Start with basic addition facts, then move to sums within 20, two-digit addition, or multi-digit calculations. The answer is checked as soon as you press Enter, so you can correct a mistake while the method is still fresh. The page works without an account and keeps scores on your device.
Addition practice levels
- Basic facts use small numbers such as 3 + 4 and build quick recall.
- Within 20 includes examples such as 9 + 8 and helps practise totals that cross 10.
- Two-digit and carrying practice uses problems such as 27 + 18, where a ones-place carry is required.
- Multi-digit addition uses three-digit numbers such as 248 + 176 for place-value and repeated carrying practice.
Timed addition test
A short timer turns addition practice into a focused challenge. Choose one, two, three, or five minutes, answer as many questions as you can, and compare your accuracy, average answer time, and best streak with your next round. For a fixed number of questions, choose Fixed Questions and select 20, 50, 100, 200, or a custom target.

Which addition range should I choose?
Start with Basic facts (1–9) until sums to ten and doubles come automatically, then use Within 20, Two-digit with carrying, and Multi-digit. If accuracy falls below about 80%, step back one range for a session. You can change the range on the Addition Practice page.
How can I get faster at addition?
Memorise number bonds to ten, doubles such as 6 + 6, and the make-ten strategy (8 + 5 = 8 + 2 + 3). Run a short timed addition round on the same small set until recall is instant, then add new facts.
What are the most common addition mistakes?
