Cathy  can I sign up for your class? Pretty please??
I was actually researching VCI and PRI and what does those indices mean in the real world. I was surprised to read somewhere that VCI correlates more with algebraic thinking and PRI with geometric abilities ie that math and verbal domains are linked as you stated. Thanks, Dazey! It's so fun to teach people who are excited about learning (that's why I like third graders .) Teaching a bunch of jaded college students taking a required course that they hate is torture. There is a math website I came across and it explained fractions just the way you did and also addressed the importance of doing so. Coincidentally, w/out knowing why or the significance of it, it's how I taught my boys fractions at a young age.
I'm not sure how significant it is, but it sure makes sense! Otherwise, kids just get a look of panic on their faces when they see two numbers with a weird little line between them. What the heck is that about? It must be hard. If nothing else, exposing kids to higher math will get them accustomed to seeing different kinds of notation. Just like we expose toddlers to the alphabet without expecting them to read right away. Why do we (as a culture) feel like we have to keep math a secret? Why do we send the message that it's "too hard" or "too confusing"?

Excellent thoughts, but if my calc student doesn't buckle down and just memorize a few basic trig points, she is going to lose too much time deriving them on her upcoming test! That's exactly why I said that rote learning can be a valuable tool for increasing fluency. And fluency is important, not just for tests, but to allow a person to glide over those concepts that have already been reasoned out. If you can't do that, it overtaxes your working memory when you're trying to reason out a new concept that builds on the old ones. Once the pathways are laid down in the brain by that initial "aha", they need to be reinforced by practice.

Cathy  that was wonderfully stated, coming from another mathematician.
I also never actually memorized anything. I can memorize things. And then immediately forget it 10 minutes after the test. How you would derive your math facts really hit home for me. I couldn't comfortably jump through teachers hoops until I really understood WHY we were doing something a certain way.
Anyway  thanks for your post.

I did learn my math facts in grade school but it wasn't exactly by rote. It was more that I repeatedly thought about them until the answers were clear. For example, 7+8=15 because 8+8=16 and 7 is one less than 8. This process builds upon itselfi.e. at some point I had to become convinced that 8+8=16 before I could use that to conclude that 7+8=15. After a while, I felt that I could skip the reasoning part and just go straight to the answer. Exactly! This is exactly what Dr. F was saying! If you get it, then the doing is easy and you learn math facts just from daily use. If you don't get it, then you're forced to rely on rote memorization for the doing, and that's painful for a GT kid. Better to start with the concepts and let the knowledge of the math facts come naturally from there. My point (I think I have one ) is that verbal reasoning can be used to understand math as a language for representing real problems. This is SO important for kids to understand. The way math is taught in school you would think that the math and verbal domains were completely seperate. I think that GT kids have the ability to intuit this connection. Mathy kids don't need to have things translated for them this way. Exposing kids like this to math is like immersing them in a foreign language. They will soak it up. Exposing them to calculus at a young age is like letting them read books with big words in them. They may not understand them right away but that's ok. EXACTLY! This is something Dr. F said, too, almost verbatim! That's why he believes ALL GT kids are naturals at math, even if they're highly verbal. Because language and math are not separate entities. Our brains don't divide math and language that way. Oh, Cathy, you're explaining this SOOOOOOO much better than I did! Thanks! This kind of enrichment is beneficial to kids at all levelswithout it, math just seems like an arithmetic wasteland to them and they lose interest. Again, right on the money. Dr. F said we should, in effect, aim high with these kids. If they don't get it all at age 6, so what? They've got years more to pick up what they missed on the first exposure! But showing them what's out there, what math REALLY isand it ain't workbooks!captivates them, shows them that math is beautiful. We don't teach kids to read by diagramming sentences, so why would we try to teach math by starting with arithmetic. Teach them to love it first, then the nutsandbolts will come. You rock, Cathy! You made that a whole lot clearer than I did!

OHG: I see what you're saying. Thanks for the clarification. I think you're absolutely right that anything can get old if done to death. Good point. It's not like math facts have the corner on that market! LOL! And I'm definitely not suggesting this style of math for a general classroom. I have no idea how that would play, and frankly, I don't really have to know. Dr. F is doing it with GT kids in a GT school, so there's that, I guess. But for my part, all I'm worried about is my own progeny! I thought it might work for some of the afterschoolers out there, perhaps in some modified form. ...Or not. You know meI'm not highly evangelical about anything I'm doing! At least it's made for an interesting conversation!

Granted, I can kind of be a laissezfaire parent, but I don't really understand the concern here. Kriston, or anyone, if your son is gifted, to the point of being accepted into DYS, is ahead of age/grade mates already in math, doesn't want or like to do math right now, and you are homeschooling so there is no need to be concerned about standardized testing or acceptance into academic programs, then.. why do math at all? Isn't the major benefit of homeschooling the ability to follow your child's lead? Well, because I don't think that it's *math* he dislikes; I think it's *my approach to math* that he has disliked. He's fascinated by engineering principles and has always had a mind for patterns and mazes that astounds me. Dropping math altogether doesn't seem like it solves anything, and may in fact mean we'd be missing some opportunities. An entirely new approach, however, may be just the thing to light his fire again, a fire that he's always had until he hit school age and workbookseither the public school's workbooks or mine. I can always back off if it looks like that's what's needed. I can appreciate some deschooling time as much as any homeschooler. But before I just give up and hope that he comes to math on his own, I'd rather try to SOLVE the problem, a problem that I feel is mine, not his. Does that make sense? He's also a lot less far ahead in math than he is in his other subjects. He's reading at the 7th+ grade level, but he's only doing 3rd grade math. I have no trouble with asynchronous development, but I think this has less to do with his abilities and more to do with my teaching. I feel like I'm letting him down, and this offers a different way to give him what he needs. It seems worth a try. And BTW, geometry, which I've approached in a far more conceptual and far less arithmeticky manner than our previous math work led us to, has been pretty successful. He's having fun with it. Geometry is one of my data points suggesting going for higherlevel, conceptual math rather than arithmetic is going to work better with him.
