Adult non-readers may prefer instructions on tape, otherwise, just describe the procedure one step at a time as they do it, i.e. teach them. Children under nine and slower learners usually need more individual attention, and should concentrate on one or two steps per session. Keep sessions under ten minutes, but encourage them to practice whenever they want. From the beginning, refer to what they are doing as 'juggling'. A continuous 3-ball pattern is not the goal, it's just another step.
Nobody needs to juggle.
So, if it's not fun, stop, and do something that is. You may NOT sell it or include it in a commercial package, put it in a curriculum, or make it a course requirement. And except for the club name and info., and the beanbag sources, you may not change any part of it, including this notice. Your comments, suggestions, and experiences are appreciated and needed.
