Door 24 is one of my favorite free iPad apps for Math grades 4th-8th. This is a super fun app that challenges students critical thinking skills as they use computational Math skills to solve different problems and help a robot put their circuits back together and solve the mystery behind Door 24. This app is correlated to Common Core Standards and focuses on different Math areas such as: Algebraic thinking, Number Sense, and more.
I highly recommend checking out Door 24 by clicking
