Hopscotch was an odd one. It was a game which adults could remember from their own childhood and so it was approved of - but not at our school! The problem was we weren't allowed to chalk on the playground and hopscotch needs markings.
These days most playgrounds have painted hopscotch pitches. I found this one at the Eden Project when I was in Cornwall. This isn't quite the same as "our" layout but there are many variations. The idea was to throw a beanbag (or whatever!) into the first square and then hop over it and continue down the pitch and back again. On the way back you stopped at square two, picked up the beanbag, hopped into square one and home. You then threw the beanbag into square two and repeated the hopping, this time hopping over square two and so on. The people awaiting their turn watched with eagle eyes and woe betide a hopper who put a toe where no toe should be or if the beanbag didn't land cleanly within its proper square as that was instantly the end of the "go". To overbalance was the end of respectability and a cue for pitying or contemptuous remarks.
No-one stopped us from chalking on pavements so it was a good game after school. I remember it especially in the long summer holidays. I actually preferred playing alone as the wait for one's turn could otherwise be very long!
