Cover Up Math

 

Cover Up Math  (Free) is a great app that works with students on solving multi-step algebra problems. To begin, the player chooses a level and pulls down the lever, which spins and gives the player a problem. 

If students are not yet fluent, they can use the "cover up" feature to work each step of the problems. These problems can be a good way to work on mental math with higher-level algebraic problems.
