Students can practice their skills of adding, subtracting, multiplying, or dividing integers by using one of these four puzzles. Two of the puzzles have 16 squares and two other puzzles have 20 squares. Duplicate the puzzle, cut the pieces apart and give either 16 pieces or 20 pieces to one student or a group of students.
1. One puzzle would have answers on every edge of every piece.
2. One puzzle would have not answers or questions along the outside edges of the puzzle.
3. Replace the four corners only of the puzzle 1 and leave all the other pieces in place. This will make it easier for students to locate the four corners.
4. Replace the 8 outside middle pieces from puzzle 1 with the 8 outside middle pieces of puzzle 2. This will make it easier than puzzle 1.
Since the two 16 piece and the 2 20 piece puzzles have the same questions you can make these switches between the two puzzles to differentiate the lesson.
