Quick check

Can the learner describe how a kitten grows into a cat, or how a baby grows into an adult?

Ask this to see whether the topic is secure.

What mastery looks like

What a learner can do once this topic is secure.
  • Describe the basic life stages of a human: baby, child, teenager, adult
  • Give examples of other animals and their young (e.g. kitten → cat, chick → hen)
  • Explain that offspring grow and change as they develop into adults

Teaching notes

From the Marble Skill Taxonomy. These notes have not been validated in classrooms, so treat them as a starting point for your own judgement.

The approach

For 6–7 year-olds: recognise that animals, including humans, have offspring that grow and change into adults. Core skills are matching young to their adults (kitten→cat, chick→hen, lamb→sheep) and ordering growth stages (baby→toddler→child→teenager→adult; spawn→tadpole→frog). Anchor in the child's own human sequence, then generalise. Contrast young that resemble the adult (kitten, lamb) with young that look completely different (caterpillar→butterfly, tadpole→frog) to confront the belief that young and adult forms are separate animals. Reproduction mechanics are out of scope at KS1.

Common misconceptions

  • 'Babies are just tiny versions of adults' — not expecting change beyond size.
  • Believing a caterpillar and its butterfly (or tadpole and frog) are different, unrelated animals.
  • Thinking all animals lay eggs, or that all give live birth.
  • Assuming animals reach adult size almost immediately rather than growing over stages.

Useful representations

  • Young-to-adult matching pairs (kitten–cat, chick–hen, lamb–sheep).
  • Ordered life-stage strips (baby→toddler→child→teenager→adult; spawn→tadpole→frog).
  • Family photo timelines for the human sequence.
  • Side-by-side 'looks the same' vs 'looks different' growth comparisons.

Teaching practices

  • Teach by matching young to adults (kitten→cat, chick→hen, lamb→sheep) and ordering the growth stages, not by verbal definition.
  • Anchor in the child's own human life stages (baby, toddler, child, teenager, adult), ideally with family photos, then generalise to other animals.
  • Keep the focus on growth and change; explicitly leave the mechanics of reproduction out of scope at KS1 per DfE guidance.
  • Contrast animals whose young resemble the adult (kitten, lamb) with those whose young look completely different (caterpillar, tadpole) to preview metamorphosis.
  • Use first-hand observation where possible (classroom caterpillars, tadpoles) so change is witnessed over time.

Activities to try

  1. 1

    Growing-up matching and ordering bench

    Why it works: Offspring grow into adults of the same kind; some young resemble their parent and some change form completely, but it is one creature changing as it grows, not two separate animals.

    1. Pair each baby animal to its grown-up: drag the kitten to the cat, the lamb to the sheep, the chick to the hen.
    2. Order a set of growth stages into the correct young-to-adult sequence; a misordered card returns to the start so the child tries again.
    3. Order the frog sequence: spawn, tadpole, tadpole-with-legs, frog, in order.
    4. Order the human sequence: baby, toddler, child, teenager, adult.
    5. Say aloud which looks-the-same animal (kitten→cat) and which looks-different animal (spawn→frog) you placed, and state that each is one animal growing up.
  2. 2

    Anchor in the child's own human life stages

    Why it works: Children experience growth in their own lives; the human sequence is a felt, familiar anchor from which the same young-to-adult idea generalises to other animals.

    1. Order your own human life stages: baby, toddler, child, teenager, adult.
    2. Bring photos of yourself at different ages (where available) and place them along the baby→child part of the timeline; for the teenager and adult stages, use pictures of older people and say that these show later stages, not you.
    3. Describe what changes between stages (size, what you can do) while keeping it the same person growing up.
  3. 3

    Reveal-the-stages growing-up strip

    Why it works: Each growth stage has a name and visible changes, and the young/adult pairs can be learned cleanly before ordering is practised independently.

    1. Tap each stage along a labelled life-stage strip to reveal its name.
    2. Lift a flap between stages to see what changed from one stage to the next.
    3. Do this for an animal whose young looks like the adult and one whose young looks different.
