    The thing that resonated with me is the idea that the unit can change when measuring something. I recall using this idea when I taught 4th grade. I said I would give everyone a candy bar but realized that I didn’t have enough so I asked if someone was willing to take a half of a bar. Once someone volunteered I took out a King size bar and broke it in half. Oh the groans!
