Play England, welcomes and recommends 101 Playground Games:

Children's play is a profoundly important part of their lives - socially, emotionally, culturally and developmentally. If they are given enough space, it also happens to be very good for their physical health and fitness. Play is nowhere more important than at school, where children spend such a large amount of time. The counter-balancing freedom and autonomy after the order and discipline of the classroom, the chance to let off steam, but also the opportunity to explore and develop vital social skills have been a key function of playtime since children have been going to school. Playground games are an important part of this tradition and a give us a fascinating insight into the world of the child. Like children themselves, these games are complex and simple, spontaneous and highly ordered, metaphorical and extremely literal. Most of all they are huge fun. Their decline is a sad indictment of the skewed priorities we place on the modern child. I welcome this book and commend it to parents and teachers everywhere.
