We use hula hoops to 'define space' for children ~ so if they want to build blocks ALONE and do not want anyone knocking them over they will build with a hula hoop as a visual reminder to others do not come in here.
We also use the hula hoops as 'basket ball nets' where the kids will hold the hoop for another child and they take turns throwing balls through them
Balls are awesome for creating 'ramps / gullies' for the balls to roll down and around
My guys rarely skip with their ropesThey get used as limbo ropes, dog leashes, rodeo lassos, snakes, to hold up their 'fort blankets by tying them to trees.
