First, I showed them an actual lambskin and let them feel and touch the soft, soft wool. I read "Charlie Needs a Cloak" and discussed the process of making a cloak, starting from shearing the sheep.
Then the fun part ... making our own sheep. The younger group just pasted colourful yarn onto a template of a sheep. This activity helps them with hand-eye coordination, practise using glue as well to enhance their concentration and patience - a good preparation for reading and writing.
