The Center for Algebraic Thinking introduces the Function Mystery Machine, a simple, yet fun way to practice algebraic functions! Choose a level or go head-to-head with a friend as you try to guess the mystery function with the help of your Algebra Machine!
This game supports algebra functions ranging from simple "x + 5" equations to ones such as quadratics and "x+a" for two-player. Function Mystery Machine is recommended for middle school students enrolled in algebra classes and above.
