I remember in 2nd grade when our teacher was teaching us how to do math I raced ahead and was doing lessons for today, tomorrow, and next week. The teacher rewarded my efforts by yelling at me and ripping up the pages from the book and giving me a 0 on that homework. In fourth grade we would play around the world with math flash cards where you raced to say the answers, and I would literally go all the way around the classroom without losing.
