Students practice adding, subtracting, multiplying and dividing fractions in these 4 puzzles. Each puzzle highlights one of the operations. Puzzles are all a basic level, where the outside edges are bland. Each 16 piece puzzle is coded with a letter to easily check the solution on the included answer keys. The puzzles create a 4 x 4 square which finishes at 9 inches. You can use the puzzles on different days, at stations or even give cut pieces to students to put together at home. Since the puzzles finish at a slightly larger square they will just fit construction paper and need to taped/glued together once the teacher has checked the solution. I find tape easier for students. Makes a wonderful display on your bulletin board.
