I remember hopscotch and rounders (where all the local kids from about 6 to 16 would join in)
We also used to do loads of skipping games which involved a massive long rope and you would have teams of kids skipping over it at the same time.
I remember playing Scissors, Paper, Stone when you were just hanging around.
A lot of time was spent building "dens" with old bits of wood, lino, branches etc, throwing ropes into trees and making swings and climbing ropes.
Another great pastime was swapping various cards we collected from packets of chewing gum.
My hubby just said the other day "there must be 40 kids up the road waiting for the High School bus but you seldom see kids playing out now." We have tennis courts, football pitches, skate park and a large playing field and you hardly ever see a kid down there.
