Most kids love to make "fortune telllers" so you could have one of them teach those who do not know how to make one.
(To make, take a square piece of paper and fold all corners to the center. Turn over and do the same. your fingers go under the four square flaps on on side, then bring your fingers together until the squares are together on top.)
Have kids draw what they think the "fortune teller" would look like from different angles, then use their own model to double check.
