Some teeth are for biting. Since many of you are getting your new front teeth, let's describe them. The new front teeth have sharp ridges on them still. Yes, in time the ridges wear off. These teeth are also called molars.
Humans have both kinds of teeth because humans eat meat, and humans eat plants also.
Remember, observations help us to make good guesses. These observations helps us sort the dinosaurs in many different ways. At the Art Center, children make dot dinosaurs. Using a hole punch and construction paper, they cut out as many dots as they need to outline a dinosaur pattern. These patterns may be used later for a wall mural.
