Check understanding
- Compare the size of a large dinosaur to a familiar object like a bus or house
- Name a very large dinosaur (e.g. Brachiosaurus) and a small one (e.g. Compsognathus)
- Use words like 'taller than', 'longer than', 'heavier than' when comparing
“Can your child tell you that some dinosaurs were enormous and others were tiny — maybe using comparisons like 'as tall as a building' or 'as small as a cat'?”
