Here is a set of ten cute, double-sided, hedgehogs that actually demonstrates the concept of odd and even numbers.

Each hedgehog has a number clearly printed on its side (from 1 to 10) and a matching number of worms on the inside. If it is an even number then there are equal numbers of worms on each side and the hedgehogs are HAPPY. If it is an odd number, the odd worm stretches between the two sides and the hedgehogs cannot decide whose it is and are therefore SAD.

The folding hedgehogs are ideal for hanging over washing lines or (if strengthened) propping up in a row.
