Play a DVD
Playing an all-time classic DVD is a good way of keeping things calmer during break time. Children will see this a real treat and may even enjoy the quiet time. This may be something that only happens now and again as it may not suit all children.
Children love to be active, and its especially important after lunch breaks to ensure children don’t become lethargic. Keeping active with some simple group play will keep them alert as well as have fun.
Play a game of duck duck goose, with a class of 30 children this can keep them entertained for quite a while. Get all the children to sit in a circle with one child walking around the circle tapping each head whilst saying duck. The child that gets called goose must get up and run around the circle and attempt to get catch the child who tapped them before they sit in their place.
If you have access to the school gym equipment, it may be a good idea to set up some throwing challenges. This can include bean bags into buckets or balls into hoops.
You could play musical statues or musical chairs. These are classic party games which are bound to keep them entertained. Sleeping lions is a great group game and will work well with a larger group of children.
These games may require more space which is ideal for play time in the school hall, or even shifting around some tables & chairs in a classroom to create a little more playing space.
