Play Dough Contest
Give each kid a tub of play dough to design his own dinosaur. You can also print pictures of dinosaurs for the kids to look at and use as a guide. The children can create their own kind of dinosaur or try to copy one of the pictures. Award prizes to the best, most creative and most realistic-looking dinosaur. For a birthday party, allow the children to use self-hardening clay. The kids can take the dinosaur home and allow it to harden overnight to have a keepsake from the party.
Digging Games
For a classroom game, fill two buckets with sand and plastic toy dinosaurs. Select two children to stand in front of the buckets. When you say "Go," they have 15 seconds to find as many dinosaurs as they can. The player who finds the most dinosaurs wins the game. Play the game outdoors for a birthday party by filling two large plastic swimming pools with sand and dinosaur toys. Have two children compete at a time by taking off their shoes and socks. The players will each get in one of the pools and use their feet to find the dinosaurs. Award a prize to the player who finds the most toys in 30 seconds.
Dinosaur Egg Games
Fill white plastic eggs with small prizes. Draw green or brown dots on the eggs to resemble dinosaur eggs. Hide the eggs around the play area and have the children hunt for them. They can keep all the prizes they find inside and the player who finds the most eggs wins an additional prize. You can also use balloons instead of eggs by drawing dots on the balloons and filling them with prizes.
Guessing Games
Fill a large clear jar with plastic dinosaur toys. Give each child a sheet of paper. He must write down the number of dinosaurs he thinks are in the jar. The child who guesses closest to the correct amount wins the jar of dinosaurs to take home. For a variation, fill the game with egg-shaped candies and tell the children they are dinosaur eggs.
