This is four by four puzzle with vocabulary words - numbers - on every side. Photocopy and then cut into small squares. Due to the margins, you may want to cut as close to the words on the outer edges. Otherwise, students will notice that those edges are larger. You can have students do this with a partner or individually. If you decide to make multiple copies, you may consider putting them on colored paper or some means of sorting them. It happens when one piece is found after the puzzles are collected. Having a way to know which puzzle they go with makes it easy to find its home.
