This is a great hands on activity to assess students solving multiple step inequalities and graphing them on a number line. The puzzle pieces will need to be cut out. Students will solve each side of the puzzle pieces. Their answers will match to a graph on a separate puzzle piece. Students will continue to solve and match pieces, until they are all matched into a 3x3 cube. You can have them glue the correctly matched puzzle pieces onto a separate piece of paper.
This is in a Word document. The first page is the puzzle with directions for students. Pages 2 & 3 are teacher's notes with step by step solutions to solving each puzzle piece.
