Your kids will love these homemade tin can drums! They can be made from recycled materials and things you already have at home. Why not make a few drums using various sized containers and listen to the different sounds they make. Or put some music on and get your kids to drum along to the rhythm and sing along to the songs.
Have a go at making your own rainbow salt tray. Toddlers and preschoolers will have lots of fun watching the colours come through when they draw pictures, create patterns and write their name in the salt. It is cheap to set up and you will already have the items at home.
