We looked at pictures from Google of dancers and then he set to work making several dragons. Each time labelling the parts as he went. 'Dragon head, dragon eye.... more dragon eye'. He wasn't always conventional about what he chose to be which part e.g. the 'googley eye's were sometimes eyes, sometimes noses (but he had a very clear plan in his head about what he wanted each thing to be). The great thing about using 'loose parts' is it can spark creativity and imagination.
When the Fairy came home from school she saw the dragons and quick set about making her own too. I love the sequins she has chosen for ears.
