Playing African Games
Many of these African games require no equipment at all to play, just some dirt and stones. Go someplace where there are dirt and stones (this may be the hard part if you live in the city, so consider going to the beach or to a campground). African games you can play in the dirt include marbles, jacks, and mancala.

If you can't find anywhere that has dirt and stones, you can still play many of the games - running races, tag (if they let you at your school), jumprope, hacky-sack, and hopscotch are all great games for any playground. If you are stuck inside, or have trouble walking and jumping, you can still play African clapping games and learn to do cats-cradle figures.
