Puzzles with Five Squares Measure the side of a small square on the squared paper on page 45. Make as many shapes as possible using5 such squares. Three are drawn for you. Game Time Here is a chessboard. Play this game with your partner, with one set of 12 shapes. The first player picks one shape from the set and puts it on the board covering any five squares. The other player picks another shape and puts it on the board, but it must not overlap the first shape. Keep taking turns until one of you can’t go any further. Whoever puts the last piece wins!
