We have lots of traditional games; some are played with songs, as ring-a-rose games, skipping or clapping games; others need specific materials, as "la goma", played with a long elastic band, or "los cromos" in which you have to turn upside down small pieces of printed paper; others are chasing or ability games, as "pedretes" or "tabas", in which you have to catch small stones in a certain way.
BUt the most interesting is that some of our project friends have some games in common: "el escondite", called hide-and-seek, "las chapas", in which you use bottle caps to do races and competitions; "el tranco", in which you have to jump some numbered squares painted on the floor...
