Door 24

Door 24 is an excellent iPad app for basic Math skills, number sense, and Algebraic thinking.  This innovative game has students using computational fluency to solve a number of equations in 6 different levels as they try to help fix Victor the robots circuits and solve the mystery behind Door 24.      This game is designed for grades 4th-8th, aligned to Common Core Standards, and has a high replay value w/ their unique reward system.
