This lovely resource idea came from Sue Graham in Busy Bees Nursery Co. Durham. She recognised how the children loved posting the various sized balls through the holes. They collected them and repeated the exercise over and over. We've therefore made Sue's idea into a resource. You can use a variety of balls. Children can see which will sit on top and investigate which will go through. This is a simple, but effective and satisfying resource that is in tune with children's interests and developmental needs. It encourages children to be curious and investigate as well as assisting fine motor skills. Made from MDF and acrylic mirror. Accessories not included. Size: W40cm x L40cm x H20cm. Suitable for all ages.
