This is how I spent many long summer afternoons in the 1960's and early 70's. Part of the fun was using colorful sidewalk chalk to draw a super good hopscotch area.
Jacks. You could always pick up a new set for under a dollar at the local TG&Y or Thrifty.
Hours and hours of play made me quite the Jacks queen in my neighborhood. Onesies, Twosies- all the way up to Fifteensies!
