How this game works
Focused practice, useful feedback
Standard addition practice combines two-digit and three-digit sums, with easier and harder questions mixed in for variety.
Reversed operand pairs count as duplicates, so a session will not repeat 27 + 46 as 46 + 27.
Calculate with less friction
Add tens, then ones
A consistent order reduces mental bookkeeping.
Use pairs to ten
Small number bonds are the foundation of larger sums.
Useful answers
Does the game include decimals?
No. All addition questions use whole numbers.
Can I practise without time pressure?
