cardboard tubes + box = hours of fun! We pieced together TP and paper towel tubes. Used marbles. The kiddo loved it and even still pulls it out to roll the marbles into a dump truck. He wont' let me toss any cardboard tubes now.
Kids would love to decorate their own rings and put their names on them. When their ring lands around the roll there could be a special activity or prize. Great idea - thanks for sharing it! DIY Paper Plate Ring Toss Game - great for kids!
