This is a fairy quick and fun project that can link in with the Stone and Iron Age or cave art. I start by preparing 4 or 5 different colours of air dry clay for the children to use. Just rip into even size chunks and hand out. They then pretend they are creating charms used to protect them or help them through life. Encourage the children to experiment with different shapes and styles and making marks with lots of different tools. Make sure they are not too small as they break once dry and make sure they have holes so you can string them up. Once they have dried and been strung up to make a necklace, I got the children to write about their charms on sugar paper and scrunch it up to look old. Some authentic Stone Age Charms!
