I remember “Chinese Jumprope” that I used to play in the Bronx. When I moved to Queens, I didn’t see it around. We used rubber bands (elastics would do) and looped them together to form one long rope that we tied the ends together. Two people would stand about five feet apart with the “rope” around thier ankles to form a large box. The jumper would put one foot in and out of the rope and then slip the foot under one end and bring it over the other side (in a way like cat’s cradle if you think of it, but you came back to the starting point) We used to sing/song “in out over one, in out over two”.. etc. There were variations as you kept going without making a mistake like turning and taking turns with each foot and the rope would also go higher too.
