Door 24 is fantastic iPad app for learning computational fluency in 4th-8th grade Math. This game has students trying to solve the mystery behind Door 24 while completing Math equations that focus on a wide range of problems (i.e. division, multiplication, order of operation, etc). W/ their unique reward system, multiple endings, and engaging narrative makes for a fun/high replay value game. Best of all, is the Math review screens that help students learn how to solve the problems they got wrong.
I highly recommend checking out Door 24 by clicking here!!!
