No ball games allowed

Given the choice most of the boys (and many of the girls) would play football in the outdoor area everyday.
Today I put the balls away and replaced them with these - beanbags with floaty bits (I'm not sure what the official name is?)
One child in particular was not impressed and initially sulked but by the end of the session, and after 3 ended up on the roof, he said "I love these, I'm going to play with them everyday!"
