I’ve mentioned Khan Academy before, but this talk really brought it to life for me: Salman Khan talk at TED 2011 (from ted.com). I’d love to get my kids using Khan’s tutorials, but I’m not sure how to persuade them to try. Maybe next time they have math homework I’ll suggest they try this instead.
I’ll give this a shot myself and see where it gets me.
Math is hard work and it occupies your mind – and it doesn’t hurt to learn all you can of it, no matter what rank you are; everything of any importance is founded on mathematics.
