I have become a huge fan of sport stacking and have recently (April) introduced it to the tweens at my library. The first time I did the program, I had 48 kids show up to learn how to stack. The numbers are dwindling a little, but the group who keeps coming is learning to be great stackers.
I tried something new with them Monday. Instead of doing our normal watch the video and stack, we did relay races and I was able to watch them individually. I am getting a core group of stacking champions already. Hopefully, we will be up to competition shape by next summer.
