Arch Puzzle

This is an intriguing puzzle for children 4½ years and older. Both children and adults are amazed by the almost magical construction of the free-standing arch. Use this material with older students to have a hands-on discussion about the keystone principle. The puzzle includes instructions, nine hardwood pieces and a wooden tray.
