In some cases, it was performing drills at all whether I'd mastered it or not. 3rd grade is multiplication tables territory. That's deadly boring even when you haven't mastered it yet. And it's one of the few times I really would advise just sucking it up and memorizing the danged thing.
I would advice to play some computer gain that trains multiplication. If you approach the problem in a gamified manner it's not boring and you will likely learn it faster.
I'd refine that- find/create a software toy that employs skinner-box methods to reward increasing skill at (withbout loss of generality) multiplying.
Although my 8-year-old son likes his teacher, he is frequently bored at school. He attends a high quality suburban public school in the United States. He has a lot of traits in common with LessWrong readers, and we would like advice for what he can do to counter his boredom. Many of you must have found grade school more or less tedious. What were your coping strategies?
