My 5th grade teacher, Mr. Lee, was one of my best teachers ever. He held some competitions for the school. One competition involved math. Specifically, multiplication. We would flip over a sheet of multiplication problems, and read off the answers as fast as we could. He would time how long it took -- I think we were disqualified if we missed any. Anyway, I broke the school record in this competition, and I was very proud of it.
Since then, I happen to remember the multiplication table for numbers less than 12, but I've decided that using a calculator is better for this sort of math. And I've felt justified in thinking this, as opposed to feeling sour grapes, because I was the best in my school at memorizing math, so nobody could tell me I hated it because I sucked at it.
My 5th grade teacher, Mr. Lee, ran a different sort of competition as well. Running. He lined everyone in my class up, and we all ran a short distance (maybe 30 feet?). I ran my hardest, and I really felt like I was going fast.. but I came in last.
I learned that I could feel like I was doing something well, but still suck at it.
