Elements of Mathematics: Foundations reviews? (x-posted) in Accelerated Learner Board Posted February 16 16 minutes ago, Not_a_Number said: Please keep us updated if you try it out! I'd love to hear more detail about WHAT exactly they do. I think AoPS is better known just because they are much bigger and because the classes have a teacher component. Will do. DS is in ch 2 of AoPS Algebra now, plugging along at his own pace. I confess that EMF seems a bit pricey to me, given that I have a math background and can offer an awful lot of help myself (all we pay for with AoPS is the textbook itself)... But I also recognize it's probably about on par (or even less) than many "deeper" options. I'm thinking of giving him the placement just to see where he'd land, but I notice that they say to start at the beginning and work through the whole thing, regardless of background. I'd really love to get him into something that would help him write proofs, because right now, that's an area where he's really struggling and we've made no real headway.
