Teacher's Notes for Magic Square Bingo

Hand out two copies of the 3x3 magic square arrays to each student. Have the students cut one of the sheets into nine individual square pieces, with one number on each piece. The pieces will fit onto the uncut array. While demonstrating a transformation of the square acting to form a new magic square, ask the class to place the square pieces on top of the old magic square to indicate their new places. This activity is great for visualization, and it helps develop geometric intuition. The teacher could perform the transformation on an overhead projector and then ask the students to perform the same transformation at their seats (see also Activity Sheet 2 and Teacher’s Notes for Activity Sheet 2).
