Ok, it's not exactly a 'math game for kids', but it's still a useful tool. Function Integrator lets you work out integration questions on your iPhone or Android device. The function integrator uses an "adaptive numerical integration technique" to quickly work out integrals involving powers, trig functions, exponential functions logs and more. Key the formula into the app, hit 'integrate', and the answer will - in most cases - instantly appear.
I've got the same integrator embedded in some function graphing software you can get for PC or Mac, and also as an Android app by following the "Function Integrator" links below, or scanning the barcodes below:
