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.
