This is an active exercise where various pages are posted up around the room. Students start at an expression and have to locate its factored form in the room. Each answer gives them a letter. When all problems are solved, the letters will spell out another room.
In that room is another set of problems. This packet has 3 entire sets of problems. The problems span from pulling out a common factor to factoring simple trinomials (a=1). You can simply use one set of problems and have this exercise span 3 lessons, or do them all at once. This is especially good for unmotivated students to experience success and get actively involved.
The letters may have to be adjusted and the problems can be updated in order to be used for future lessons.
