What happens at break has an impact on lessons. How many teachers spend the first 10 minutes sorting issues dragged in from the playground? One idea that might be making a comeback is singing.
Playgrounds used to resonate with songs, rhymes and clapping games, but they have been neglected and displaced. Singing Playgrounds, a new project, aims to revitalise the oral tradition.
At Lawn Primary, my school in Derby, the place is alive with sounds such as Here comes Sally walking down the alley, A sailor went to sea, sea, sea, and Have you ever, ever, ever, in your long-legged life.
We are one of 24 schools taking part in the first year of a national project, run by Ex Cathedra, a Birmingham choir. Vocal tutors from the choir led an inspiring community-singing assembly and then visited each class. But the most important people are the song leaders - pupils trained by the Ex Cathedra tutors to lead the singing games in the playground. These youngsters visit the infants to share games with younger children in their playground.
"It's good to have the responsibility and the chance to teach the infants and show them what to do," says Daisy Allen, a Year 5 song leader.
Soon the children are bringing to school rhymes and actions suggested by parents and grandparents - The Grand Old Duke of York, Oranges and Lemons and The Farmer's in his Den.
My Year 4s have enjoyed practising some of the songs and rhymes in class. Children then go outside to develop the songs in groups by choreographing their own actions and routines.
Before you know it the playground is singing. Self-esteem is greatly improved as pupils shed inhibitions and find their voices
