We called it Red Ass (or Red BUTT, since we weren't allowed to swear). The school I went to from grades 2 to 4 had a wall that was perfect for it, since it was huge, no windows, and it was impossible to roof the ball.
Played a lot of World Cup basketball, which was the same as World Cup soccer, just transfered over to basketball. Playing as teams of 2 was usually better. A lot of foot hockey or ministick hockey with tennis balls was played, too.
The best, though, was football in the snow. Grade 5 was the best year for that, since there was this huge field in the school yard and a lot of snow that year. We could tackle each other and shit without worrying about grass stains or anything else our moms could get mad at us about.
