Dinosaur Sizes
Compare dinosaur sizes to familiar things — some dinosaurs were as tall as a house, others were as small as a chicken — and understand that dinosaurs came in a huge range of sizes
Lesson
Set out your lesson
“Dinosaur Sizes means comparing dinosaur sizes to familiar things and noticing a huge size range. We will practise once together, then check a fresh example.”
Bring to the table
- Room references: doorway (tall), toy chicken or shoe (small)
- Two dinosaur pictures or sketches: huge vs tiny
Extra for the adult
Worked example. A giant sauropod could be house-tall. Some small dinosaurs were nearer chicken size.
Optional challenge. For Dinosaur Sizes, invent a third compare (bus-long) for a long dinosaur.
What to notice. Keep one parent note: size compares; range idea; support used. This session samples dinosaur sizes, not mastery of every dinosaur.

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'?”
