Collect the containers from the small yoghurt drinks. You need one for each child. Half fill these with a variety of objects, such as lentils in some, chickpeas in others etc, until you have about 5 or 6 groups.
Play ‘Find That Sound’, where the children seek out others with the same sound. Once the children are in their teams, you have an orchestra!
You can make up a variety of rhythms, explore stopping and starting, loud / soft, fast / slow etc.
Make sure the objects make a reasonable sound… porridge is too quiet!
