MATH DINOSAUR EGG HUNT: Hide plastic eggs with numbers in them. The numbers should range from maybe 1 to 5 depending on the age of the kids. Limit the number of dinosaur eggs each childd may find. Like about 6 or something. Then, after they're all found, total up the numbers that are in their eggs. The one with the highest number wins a prize. Have plastic eggs with candy in them too, so that everybody will end up with something.
