Roll up! Roll up! The Perform Circus app has come to town so take your seats for the Greatest Show On Earth. Children can enjoy flexing their creativity in Clown Face, putting on a show in My Big Top, honing their coordination skills as the Circus Ringmaster and developing their concentration in Amazing Acrobats. They can also enjoy a selection of lively videos featuring circus songs, dances, raps and tongue-twisters to watch and join in with at home.
