When I was a kid, my mom had this cube made of different sized pieces of hard green plastic. Each piece was unique; some had right angles, some had a right and a left turn in them, maybe one was straight. But when they were all put together correctly, they formed this cube that fit snuggly into its plastic case. I worked and worked on this puzzle. It seemed I didn’t have enough fingers to hold the pieces in place to try to fit a new piece in. At first, I would get two pieces that seemed to fit the right way, then I’d add another and drop it, then I’d start all over again with those same first two pieces, slowly putting together the puzzle once piece at a time. I made it; the pieces were transformed into a cube! Soon, I could put it together in record time.
