1. Egg Shells - start saving your egg shells. Wash them and keep them in a zip-loc bag until you have enough.
2. Go online and have your child pick out a t-rex image on google to print. I just typed "t-rex coloring sheet" and a bunch of images came up.
3. Cut around the shape and glue it to construction paper.
4. Start smashing and crushing the egg shells while still inside the zip-loc baggie. Keep going until they are in small pieces. Good way to build finger strength.
5. Pour white glue on a paper plate and have your child "paint" the glue on the shape, then sprinkle the egg shells on top.
When it is dry you can talk about how rough the skin is on their t-rex and don't forget to practice their "roars".
