Free math games for classrooms. Runs in the browser, nothing to install or sign up for.
Math Squares is a browser version of dots-and-boxes where every move requires solving a math fact. Pick a game: multiplication, addition, subtraction, or division. Spin, solve, find the answer on the board, and draw a line on one side of that square. Close all four sides and you own it. Most squares wins.
Students aren't practicing math as an exercise. They're hunting for squares because they want to capture them. The math is just how you get there.
Spin to get a number, solve the problem for your game, find the answer on the board. Draw a line on one side of that square. Once your opponents realize they can block you, it stops being about math at all, and the math practice keeps happening anyway.
Addition and subtraction are aimed at Grades 1–2. Multiplication and division at Grades 3–5. Each game has multiple difficulty levels. It works for 2 to 4 players, so it fits partner work, small groups, or a projector demo with two teams.
Every other version of this game needs printed worksheets. You know the routine. This one runs in a browser tab. Open it and you're playing in under a minute.
A former classroom teacher built it because every version online was either broken or paywalled. No Flash, no account, no cost.
There's a printable version. Pick a game and level, generate a board, print it. The layout randomizes each time so students don't memorize where things are. You need a spinner or dice and colored pencils, one per player.
