Equation Decoder
Students solve a series of 20, one step algebraic equations involving addition, subtraction, multiplication, and division to decode a secret message. Each solution matches to a letter of the alphabet and when put together gives the message "equations are exciting"! Comes with an answer key as well. Great for algebra review. I like to use it for team races; each team gets one paper and tries to finish as quickly as possible with each team member solving one question then passing to a teammate.
