Well he's old enough to read so maybe he could do story time with the younger ones, help them with a craft, playdoh, or maybe he could make up a game of follow the leader with the kids tO get them moving..... I have an 8 yr old son and he likes to help.... Organize clean up, a game, help get snack on the table, ect .... Sometimes he puts all the kiddie chairs in a row and he dies a game of wheels on the bus with the kids , that are all sitting in chairs doing the actions and singing
