The Chinese call this geometric puzzle Qi-Qiao Ban, which may be interpreted as "seven clever pieces." It's easily made by repeatedly folding a square of paper in half to create 16 smaller squares and then cutting the open sheet along the bold lines as shown. With the seven cutout shapes, you can make hundreds of designs. To celebrate 1999, the Year of the Hare, see if you and your kids can piece together the critter shown.
