There a many things you can do to provide recess entertainment for the younger set without breaking a budget or spend too much.
Though handballs, sandbox toys, and jump ropes are nice, it's not completely necessary to have, nor do you need to purchase that many.
Permanently paint lines for hopscotch on concrete. Purchase concrete-safe chalk for kids to doodle and draw on the ground (it'll wash off in the rain or from a hose).
To maximize the use of toys such as balls, AGAIN, make good use of available concrete spaces! Have lines painted on the concrete for the game of "four squares" where four kids can play simultaneously with the ball as opposed to just one or two. These multi-player games can also help encourage social interaction and development with everyone on the playground.
Try those out!
