In relation to dinosaurs, children learn about diet, size, biggest, longest, defense mechanisms, body shape, possible sounds, distinguishing characteristics of specific dinosaurs, interdependence, extinction, timelines, pronunciation, and name derivation.
Children have experience in movement to a beat, movement to a rhythm, structured dance, "echo" singing, counting forwards and backwards, addition, simple categorization, song structure, and simple comparison terminology.
But most of all, they enjoy themselves.
