I’m behind the times and don’t even know what it is. But, they do it in math class in the 5th grade now. It’s a puzzle game. Really! We participated in grandparent’s day at school. It’s not what it used to be (school). In fact, the gym was bigger than our entire elementary school. Yes, we went to the same elementary school – Elkins First Ward. The principle shoveled coal to keep us warm. And that darned school was smaller than the gym. In fact, we had no gym. Our exercise was in the yard of barren grass not the tennis court this school sported. Yeah, strangely different after decades. Progress.
