Students pick a puzzle piece and pick a problem that is not in simplified form. Students will use the distributive property and combining like terms to find the simplified form. Then, they will find the answer among the puzzle pieces. Next, match the edge of the problem to the edge of the answer.
The pieces may be pre-cut for the students, or have the students cut the pieces themselves and then assemble the puzzle.
