Find a space outside that has some trees that are dropping their leaves. Select a leaf from the ground and station yourself a small distance away from where you choose the leaf if possible. Then ask the kids to find a leaf that is:
- The same size as your leaf
- Has the same shape
- Has a different shape
- Is the same colour
- Has two different colours on it
Be creative and think of new things that the kids can find on the leaves on the ground that are similar or different to the ones on your leaf.
