Learn when and where dinosaurs were discovered, and how many millions of years ago they existed. Imagine the size and weight of each dinosaur relative to you! Practice pronouncing each name and then color in the dinosaurs. Tot Talk's double sided, educational placemats are thick and high quality. Use washable markers, and wipe clean with wet paper towels, or wash with warm water and dish soap for bacteria free learning. For extra fun, give your child a spray bottle, and they can spray it, and wash off their work and start over.
