Mustard Math Apk v4.0  

We made this game to help students practice their maths! We won
the Congressional App Challenge with this game!

Dodge asteroids, pick up trash, and answer math questions!

This game is suitable for students of all grade levels. It starts out giving simple problems, but as you answer them correctly, the difficulty increases and you get tougher questions. The difficulty is saved, so if you close the game, and then open it again, your "level" or difficulty level will stay the same.
