It's not as entertaining as GEB, and requires a fair amount of patience to think and work through some of the problems. But I think it is rewarding as it gives multiple approaches to answering questions about why some results are true. For example, as to the question what is the pattern of 1, 1+3, 1+3+5, ..., they give both algebraic and geometric formulations of the problem.<br /><br />I am not a theorist, but I sometimes write about my (often frustrating) experiences with theory in the "problem solving" and "learning" memories of my LJ.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-85404293267925865602009-09-27T12:59:29.405-05:002009-09-27T12:59:29.405-05:00Many thanks to Chris.

At the time, I knew very little 'real math' and I was mainly reacting to the excellent popular writings of Gamow, Feynman, etc.<br /><br />As I have grown up and looked at some real math, I find that one of the most fantastic things about it is its utility in the description and analysis of phenomena that would otherwise seem too vague. Perhaps it is not a bad idea to introduce children to this idea (in conjunction with the notion of pure math as the ultimate form of entertainment).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-85734705235989290572009-09-26T00:42:09.986-05:002009-09-26T00:42:09.986-05:00The thing that got me into math was a love of puzz...The thing that got me into math was a love of puzzles. I always kind of liked math somewhat but the Junior Waterloo Math Contest problems for grades 9-11 (and the MAA contest) really hooked me - multiple choice problems on a varied range of combinatorics, simple algebra, geometry, and logic. I would work on copies of old contests during my other classes.<br /><br />The funny thing is that though these math contests got me into the field, I now have little patience for doing math puzzles of the sort where someone else already knows the answer.Paul Beamenoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-87224030891606798582009-09-25T17:35:25.054-05:002009-09-25T17:35:25.054-05:00I loved A.K.Dewdney's The Planiverse .

Like Flatland, it looks at life in a two dimensional universe, but goes way beyond Flatland in terms of exploring what engineering, physics, biology, and chemistry would look like in a two dimensional world. How would you play volleyball in a two dimensional world? What sorts of vehicles can you build? How does a two dimensional body with a digestive track avoid falling apart?<br /><br />Flatland was written as a social satire and, even with that in mind, can be hard to stomach at times. Parents whose kids read Flatland will need spend significant time explaining the satire, as opposed to the mathematics, including the extreme sexism and social hierarchy of the Flatland society. The satire has its value, but is not necessarily what readers expect when they pick up a book that is famous now almost entirely for its mathematical content.Unknownhttps://www.blogger.com/profile/09358937783900380398noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-84193663805727057792009-09-25T15:19:23.108-05:002009-09-25T15:19:23.108-05:00Physics was (and is) my main motivation for math, ...Physics was (and is) my main motivation for math, though there is a lot of neat pure math as well. <br /><br />In <a href="http://scottaaronson.com/blog/?p=410" rel="nofollow">this post by Scott Aaronson</a>,he links to and discusses <a href="http://www.maa.org/devlin/LockhartsLament.pdf" rel="nofollow">a paper by Paul Lockhart</a>, of which I have only read the first few pages, and it is more about what is wrong with math than how to do it right (I think).

Whether your child actually "competes" or not, you can download the exams from the web to give him something challenging to work on.<br /><br />If he's interested in fundamentals of computers you can try "Elements of Computing Systems..." by Nisan.

Book" and its somewhat more advanced sequel "Math for Smarty-Pants".<br /><br />I <i>devoured</i> these books in early elementary school. They are full of zany comics, fun activities/experiments/puzzles/magic tricks with surprising mathematical depth, and great concepts that they don't teach in school: Mobius strips, perfect numbers, "huge" numbers (e.g., googol and googolplex), the Josephus problem, etc.<br /><br />The book also poses problems, some of which end up being very deep. (Some have even been open for centuries!) I remember thinking about whether all perfect numbers are even, and that led to all kinds of independent explorations and discoveries in number theory. I can't praise these books highly enough.Chrishttps://www.blogger.com/profile/03327470068256472110noreply@blogger.comtag:blogger.com,1999:blog-3722233.post-3919956840606177282009-09-25T08:06:52.115-05:002009-09-25T08:06:52.115-05:00Many math-loving people got their start reading Ma...Many math-loving people got their start reading Martin Gardner.<br /><br />The Art of Problem Solving books make me wish I had learned from them when I was younger http://www.artofproblemsolving.com/<br /><br />Like Lance, I had no idea what real math was like or that I could do it until partway through undergrad. The key for me was not "big" inspiring questions but rather learning that I could solve "small" ones with just a little flash of insight, and it was only a lot of solving little questions that gave me the confidence to pose my own. This is not something that I would have figured out how to do on my own, or even if my parents had handed me a book or two (though that might have helped).<br /><br />Your child may enjoy learning to program, in which case something like http://projecteuler.net/ might be fun (but a bit much for junior high math).Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-3722233.post-3612653312990353292009-09-25T07:58:28.459-05:002009-09-25T07:58:28.459-05:00I was a perfectly capable math up until my first g...I was a perfectly capable math up until my first go-round as an undergraduate.
