Fractonio's Pizzeria (pizzas and fractions) - purplemash

Fractonio's Pizzeria is a neat game,  the player needs to serve mixed topping pizzas upon customer requests and avoid a queue building at the shop. It's a game to practise fractions, but not to learn about fractions from scratch. It comes in 3 levels of difficulty and I thought interest on it would wear out quickly but I see it being used quite often by the little ones - I think the time challenge makes it interesting.

Factoroids - Purplemash

Factoroids is a great game. Remember Asteroids? Just that instead of a spaceship versus asteroids it's a calculator versus number blocks. You can shoot at them, but they will only break if the bullet is a factor of the block. Great time pressure cum motor skills cum times table knowledge! It has a couple levels to choose from.
