This is a fun activity to review solving for the variable "x". Two different riddles and Teacher Directions are included in the file. Each riddle has 8 problems to solve.

Teacher Directions: Students will solve each problem for x. Then they will go around the room and find what letters correspond to the x to complete their riddles.
Before you start, make sheets of paper that are folded with the number on the outside and the corresponding letter on the inside. Tape the letters around the room to get the students moving!
