What a learner can do afterwards

  • 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

The lesson

Dinosaurs came in many sizes. Some were tiny. Some were huge, taller than a house.

Compsognathus1House6Brachiosaurus12
Brachiosaurus was taller than a house. Compsognathus was tiny, like a chicken.
Try it together

Mia stands by a Brachiosaurus skeleton. It is taller than her house! Then she sees a tiny Compsognathus. It is about as small as a chicken.

Good to know

Use words like taller than or heavier than. This helps you compare dinosaur sizes.

Dinosaurs ranged from house-sized giants to chicken-sized tinies.
