It is easy to forget Spanish words when you learn a pile of them in half an hour. For my Wednesday Spanish enrichment class, I decided to review with a cube puzzle. On a grid, I wrote a Spanish word we learned and the English translation on each line. I cut out the squares, and challenged the kids to match them and recreate the square.
It went well! With the larger classes, I might recreate this onto larger squares and have them do a floor-size version in a Spanish-meets-teambuiding adventure.
