This engaging activity is great for students as they're practicing their skills of combining like terms with rational numbers. Students are up and moving around the room, simplifying expressions, while working with a partner (or they can work alone!). There are 12 stations the students will visit, and the answer the each station will lead them to the next station. It works in such a way that they can start at any station, and if they solve all the problems correctly, they should end up at the problem they started at. An answer sheet for the students to use is included, as well as the answer key for the order the stations should go in.
