When I was a child, girls did handstands, cartwheels and so on with their skirts tucked into the lower edge of their knickers. Very little underwear was on show.
Games came and went in waves - one week everyone was skipping, a few weeks later everyone was playing marbles, a few weeks after that it would be hula hoops, or jacks (5 stones), or throwing a ball against the wall and performing various variations (throwing it under the knee, clapping, letting it bounce, turning round before catching it ...). Some of it would be seasonal, such as conkers in October.
Nowadays there are newer crazes unknown in the last century but they may not come back so regularly. A couple of years ago, suddenly every child had a fidget spinner, but I haven't seen one for a while now.
