Key learning

In this lesson I have learnt that: In the animal kingdom, there are five vertebrate groups: reptiles, birds, amphibians, fish and mammals. Some animals are invertebrates, like insects. Animals grow and change throughout their life cycle.

They might get bigger, grow taller, change colour or shape, grow limbs and live in different places.

Homework Find out about other animals and their life cycles. Draw the life cycles and share information about them with your classmates.
