Animal Life Cycles means comparing life cycles—direct development vs metamorphosis—across mammals, birds, amphibians, and insects. We will practise once together, then check a fresh example.
Spend about 12 minutes sorting life-cycle cards and saying one difference, then checking a fresh cycle.

Check understanding
- Describe the life cycle of a mammal, amphibian, insect, and bird with key stages for each
- Compare metamorphosis (complete change of form) with direct development (gradual growth)
- Identify which groups undergo metamorphosis and which do not
“Can your child explain how a butterfly's life cycle (egg, caterpillar, chrysalis, butterfly) is completely different from how a puppy grows into a dog?”
