Free Addition Facts Games
Every question is an addition fact, and every answer moves something: a block, a rocket, a train.

Why a game beats a page of sums
A page of sums gets done once. A fact only becomes automatic when a child pulls it from memory many times, spread across many days, and that's hard to ask of a worksheet. A game gets those repetitions without a fight: a child chasing a prize will happily answer fifty facts and ask for another go.
Sumtown also teaches in a sensible order. It starts with adding 1 and 2, moves to doubles and pairs that make 10, and only then asks for the harder facts that cross 10, which lean on what came before. See the strategies.

Addition facts FAQ
What are addition facts?
The basic sums a child learns to know without working out, usually every sum of two numbers from 0 to 10. There's a chart of them all.
What are the best free addition games?
Look for games where the math drives every move, that adjust to your child, and that have no ads between questions. We wrote a guide to fluency that explains why those matter.
What order should addition facts be learned in?
Plus 0, 1 and 2 first, then doubles, then pairs that make 10, then near doubles and ten-plus, and finally the facts that cross 10. Our teaching guide walks through it.
Is Sumtown really free?
Yes. The whole game plays free in your browser, with no signup, no ads and no time limit. All fourteen mini games are in it. An iPhone app is on its way, and you can read what it will add.
An app is on its way
We're building a Sumtown app for iPhone with the parts that need a real app: offline play for car rides, a town map that remembers how far your child got, and a parent report on every fact. Until then, the whole game is free right here.
