MathBoard

Forget the cutesy characters and sweet sounds—this is the mother of all math apps, and she's not fooling around! With a staggering array of settings and thorough help guides, this app represents an ambitious attempt to create the preeminent math teaching tool.

The choices don't stop at multiplication or division, cubes or squares, easy or hard. You can choose a specific number range. You can do multiple choice or fill in the blank. Want to add a countdown timer to the challenge? You can do that too. Negative numbers? Yep. Digit limits? Yep. Enforce range on dividend? Sure, if you know what that means. Whether you want simple addition practice or a timed quiz for square roots, you're covered. The only downside? Don't expect a kid to load this app and get involved right away, especially with an unexciting chalkboard theme.

The options satisfy a wide range of students and skill levels, but they can be overwhelming for kids or adults. MathBoard would be best used in the classroom after a math teacher has tailored the settings to a specific purpose. To experience this app's versatility before dropping $4.99 on it, try the free version, Mathboard Addition, which is limited to just addition problems but still boasts the same options and help guides.
