[QUOTE="InsaneCdn, post: 479434, member: 11791"] First idea is that the teacher needs to wake up and get herself into the 21st century. Seriously. This is absolutely classical working-memory problems. No, he CAN'T memorize it. Doesn't work. He will NEVER have instant-recall on math facts. Ever. And if he does manage to cram it in his head this year? It will vanish before the next year starts. I couldn't either. Still can't. So please explain how knowing math facts impacts math knowledge and skills? I pulled 80s and 90s in math right through HS. 1) He needs to learn the strategies, not the facts. The rule of 9, for example. The rule of doubling. The rule of tripling. If I'm not missing one, that should leave ONE fact to memorize: 7x7. (if you don't know the rules, ask). This enables him to PROVE that he knows what he is doing, allows for learning approximation etc. 2) Once he's got the strategies, then he needs to get one of the smallest original hand-held computers ever made. Its called a [I]calculator.[/I] Best thing ever invented for math-fact-challenged people like me. [/QUOTE]
