Instructions

Tiny Steps

Get ready
  • Find a tree and ask your child to hug it — wrap both arms around the trunk.
  • Can they reach all the way around? Say: 'Your arms are not long enough! This tree is very big.'
  1. Find a tree and ask your child to hug it — wrap both arms around the trunk.
  2. Can they reach all the way around? Say: 'Your arms are not long enough! This tree is very big.'
  3. Move to a thinner tree and try again: 'This one you can hug all the way around!'
  4. Wrap a scarf or string around the first tree and cut or mark the length.
  5. Try the same string on the second tree: 'Look — there is string left over. This tree is thinner.'
  6. Visit 3-4 trees of different sizes, ordering them from thinnest to thickest.
  7. Talk about the bark texture: 'This one is rough. This one is smooth. Feel the difference.'
  8. Finish with a favourite tree hug and say goodbye.

Parent tip

Start before you overthink it. No-prep activities work best when you begin while the moment is still recoverable.

What success looks like

Curiosity in action — pointing, collecting, asking ‘what’s that?’ A child engaged with nature is learning without knowing it.

Your child wraps their arms around a tree trunk and discovers whether they can reach all the way around. They try different trees — thin saplings, fat oaks, medium birches — and compare. Using a scarf or string to measure adds a tool-use element and makes the comparison tangible.

Why it helps

Non-standard measurement (using arms, scarves, hands) builds the conceptual foundation for understanding that measurement compares one thing against another. The Woodland Trust highlights that tree-based activities develop spatial reasoning, size comparison vocabulary (thinner, thicker, bigger, smaller), and a personal connection to the natural environment. Speech and Language UK recommends this kind of back-and-forth interaction as one of the simplest and most effective ways to grow a toddler's vocabulary.

Variations

  • Count how many of your child's hand-widths fit around each tree — introduces non-standard measurement.
  • Bring paper and crayons for bark rubbings — press paper against the bark and rub over it to capture the texture pattern.
  • Challenge older toddlers to find the thinnest tree they can reach around and the thickest they cannot.

Safety tips

  • Check bark for thorns, sharp edges, or insect nests before hugging.
  • Avoid trees near roads or on unstable ground.
  • Teach your child to hug gently — pulling bark off can harm the tree.
