Write a story that incorporates as many sounds as possible.
For each sound used in the story arrange to have a group of children make that sound. As the story is read out each group makes his or her noise as the appropriate moment. Telling a ghost story is one idea for doing this, or farm yards, zoos, etc. It’s also fun to each story several twice using the first reading as dress rehearsal. You could also get players to make appropriate actions to add to the fun.
