Math reaches every thing. I am completely puzzled by this comment. Physics is everywhere in everybody's everyday life. How a ball flies, how a car drives around a curve, how it stops, how the Earth revolves around the sun, ,why there are seasons and tides, how your computer and your stereo work, how your cells let the sodium and potassium ions in and out, how your brain tells your foot to move, how your eye sees, how a telescope works... how is that "niche" and doesn't reach everything? Every object, every organism, every cell and cell organelle, every planet and every elementary particle is subject to the laws of physics. ETA: I would not stop math. I would seek out resources to learn math off the beaten path. Have you completed AoPS' number theory and counting&probability? Great topics, books written to the student so that no outside instructor is necessary. Edited October 27, 2018 by regentrude 9 Share this post Link to post Share on other sites

Can you explain what you mean by "such small returns"? Either they understand and learn what you teach them, and then the return is huge. Or they don't, or only through a tremendous effort on your part, because the material is not developmentally appropriate - in which case I would question what the point of this relentless acceleration is supposed to be. 1 Share this post Link to post Share on other sites

mumto2 30,100 Report post Posted October 28, 2018 We made several passes through most math topics in an effort to slow my kids down so I understand what you are saying but I would want them doing math for an hour or so a day. It is easy to get out of the habit. My kids were not fans of AOPS either so used it as prep for math competitions but otherwise ignored it. We always did the LoF book first for topics after we discovered them because my kids really loved Fred and I know there is now at least one book beyond Linear Algebra, that might be a fun option. Dd always enjoyed applications books like Lial’s Applications in Calculus because she enjoyed seeing how Calculus is applied in many fields. Yes, it is treading water but in a way a bit extra is learned. I know we several applications books. 1 Share this post Link to post Share on other sites

Honestly, it sounds like you're dreading the change almost as much as, or more than teaching physics. Any particular reason why you're even trying to teach physics next year?

lewelma 13,417 Report post Posted October 29, 2018 (edited) Gil, have you considered allowing them to self teach? They are young, so you would need to supervise in some manner, but self-teaching is such an awesome skill. During high school, my son designed his own math courses, set goals, managed his work load, self-taught, and self-managed. He did NOT do this in 7th grade, but it might be a goal you work towards for 10th. The person we need to get onto this thread is Butler. Is she still around? Her kid was crazy accelerated like yours. Her and Quark. You have accomplished so much and in a difficult environment. My hat goes off to you!

mathnerd 3,407 Report post Posted October 29, 2018 Your sons are way ahead of even where you envisioned them to be at this age! I think that you need a break from that level of prep work. It is a good idea to not take a complete break from math. How about finding ways in which they can apply their mathematical knowledge to problem solving? Some ideas are solving competition math problems (self paced and solutions available online in case they need to validate answers), computer programming using various algorithms and data structures (they can work on their own on a long term project), mathematical logic study etc. I am sure that posters like Kathy will be along to give you more ideas. But, I cannot envision prepping to that level to teach any subject and the maximum that I have done so far is to use multiple resources and winging it! As lewelma said, you are an awesome math teacher! Take care. 2 1 Share this post Link to post Share on other sites

kiana 11,412 Report post Posted October 29, 2018 I like the self-teaching or reading idea. Some subjects are highly conducive to this. There are also some books designed for self-study where there are fully worked solutions available. History of Math (there are some really good resources out there now) might be interesting. There are some hoary old classics, such as E.T. Bell's Men of Mathematics, which (as a product of its times) has problems with several -isms, and yet has inspired multiple highly regarded mathematicians. There are many newer books as well. Stephen Hawking has "God Created the Integers", which leads interested readers through several genuine masterpieces (full disclosure -- this is still on my amazon wishlist). Ian Stewart has a LOT of good books. Kline's Mathematics and the Physical World would be an interesting segue into physics before you go for a full-fledged course -- they're beyond the math in it, I'm sure, but it goes through a lot of applications. It's also a Dover book so it's super cheap. Kline's Mathematical Thought from Ancient to Modern Times is also a great mathematical history. I'm going to shut up now but I could keep dumping for ages. In case it's not obvious, I'm kind of a book hoarder. A local math circle might be interesting if you can find one. You'd probably have to find an out of level one. Long-distance mathematical penpals might also be interesting. From where you are, you might also be able to find a local math professor or graduate student who would be interested in weekly tutoring sessions, with the idea that they'd supplement between -- even if you can't afford it, you might be able to snag someone who's willing to do it just because it's a thrill to have highly talented students who like math. You could call a local university's math department and ask. When you do decide to return to proofs, I'd look for something where you can get an instructor's solutions manual. One that's now open-source would be a good choice -- https://aimath.org/textbooks/approved-textbooks/ has several textbooks that were originally published but are now out of print and copyright has reverted -- and you might well be able to get an ISM from the author by explaining your situation. But with all that I've said above, I don't think it's going to do them any harm to take some time *off* math. I still think that I'd make sure that there were interesting math books around. Again, you might contact a local university and ask if any of their professors have old books floating around that they'd recommend. I picked up some of my most interesting supplemental reading books from a professor who was retiring and "get this out of here". 1 Share this post Link to post Share on other sites

RenaInTexas 315 Report post Posted October 29, 2018 (edited) They are at a level where they could likely teach themselves from most math books. Some ideas would be: operations research analysis, abstract algebra (this could be awesome, I loved it!), game theory, numerical analysis. They could also venture into some areas where higher levels of math are used like: aerospace engineering. control engineering, learn Matlab. Another idea could be to subscribe to a math journal (like AMS) and have them read from there and maybe take a deeper dive into an article that grabs their interest. Older issues are free on the website. (Another journal) The challenge for them is to learn from the text and similar resources without help from mom. The challenge for you is to let them learn from those resources and not you. You take the perspective that it is more so about learning to self-learn than about learning the math/content. BTW, I feel the exact same way about AOPS, but I never dared to say that here bc so many here adore it. I keep looking at it for my own kids and all I see is what your kids see.

I'd love to learn from your experience. Very curious as to when they started, what curricula/books you used, what material got covered when (e.g., 3rd and 4th grade in one year, etc), daily math routine, participation in any math enrichment/competitions outside the home, etc. You will now have so much time to cover other exciting subjects before the boys leave home!

As my daughter put it after her run through the Calculus book, she will never have any fears about Calculus again but definitely needs more to complete the typical course. I think the easy introduction is the benefit. I don’t think the elementary ones really show the quirky Fred at his best...I thought they were rather blah when I read part of one at a friend’s. For the most part they are an introduction to the harder math but Trig stood on it’s own just fine.

So I am looking for suggestions for some good "dabbling" math books/series written between a highschool or university sophomore level. I'm actually pretty intrigued by the university level Life of Fred books. I think that Buddy could go either hate/love with them. He has a ridiculous sense of humor, but is 100% against anything that is "babyish" and finds "gimmicky" unappealing. But he has an absurd sense of humor (his Nanowrimo story is about an immortal goat who is the worlds greatest mathematician) so...maybe? I think that Pal will be entertained (possibly distracted) by the goofiness of the layout and story, but he'd at least finish the book. From reading the samples of Calculus, Real Analysis and Linear Algebra, I know those books would make me nuts. I'm firmly in the hate it camp--but I think I'm going to get them one anyway. We've done a lot of math over the last 7 years and I'm kind of at a loss of where to look next. Next year, our math class will be different in at least the following ways:. 1) Won't require a lot of prep for the teacher (ie Me) 2) Not focused on "harder" math (ie going to the next level in a sequence) 3) Not assigning every problem in the book, but it would be nice if it had some problems for us to work on. 4) No going willy nilly down rabbit trails. After 6+ years, I can say that 'willy nilly' just doesn't work for us. 5) 2-1. They're eager to do weekly presentations on mathematics concepts. So each of them will have one math-centric speech/presentation/demonstration each month 6) Organized around units, we'll be spending 2-6 weeks with a book/source/topic? 7) Minimal homework for them I really want dabble-ready stuff that we can get through or set aside after 2-6 weeks. We've worked off and on Dovers Challenging Problems in Algebra/Geometry, and Competition Math for Middle School there isn't enough left in either of those books to keep us for a year. So I'm thinking the Five Days LOF might be an interesting addition to the pile for 2019. Any thing else you'll can think of? It needs to be print or readily printable, but print books are preferred by a long shot. ?. Considering Fred’s pet Llama destroys a football field at the start of Geometry this could be a good match. All sorts of really absurd things happen in those books. Share this post Link to post Share on other sites

kiana 11,412 Report post Posted November 10, 2018 Dover, Flegg's From Geometry to Topology. I used this as an adjunct to a topology class that I was teaching in an effort to try to make these complicated concepts more intuitive. The author was intending it as a prologue to a university course (in the UK, so they would already have passed their A levels) or a supplement for interested students in the sixth form (11th/12th grade, taking A levels). No real chapter exercises, some exercises at the end of the book. More Dover -- the book Sequences, Combinations, Limits, by Gelfand (not I.M. Gelfand, different one) et al.22 Many books from the Anneli Lax New Mathematical Library -- some specific titles could include Coxeter's Geometry Revisited (you can find this online for a preview if you look in the right places), Niven's Mathematics of Choice, Beckenbach's Introduction to Inequalities, and there are more.

kiana 11,412 Report post Posted November 10, 2018 (edited) This abstract algebra text was designed for students who really hadn't had a formal proofs class -- they've had linear algebra, and done the proofs there, but not much more: https://www.amazon.com/Abstract-Algebra-John-Beachy-ebook/dp/B00GUOBNFG/ref=cm_cr_arp_d_product_top?ie=UTF8 The authors also have a companion website, with supplemental problems, a lot of which have solutions here: http://www.math.niu.edu/~beachy/abstract_algebra/ *I* thought Fraleigh was very good for an undergraduate introduction, and having taught a one-semester abstract algebra class out of it several times, I find that it has really helped my *own* complete/thorough understanding of the material as well. As you know from your preparation, there is a huge difference between having a decent understanding of a subject as a mathematics student and having a decent understanding as the instructor. It may be too advanced for what you are looking for, but I mention it. There are some really interesting sections in it -- Chapter 12 (he has "chapters" where many would have "sections" in particular has some very interesting stuff on plane isometries. If you (or anyone else who's reading this thread) go for this one and want some answers checked, pm me -- I've graded many of the homework problems before and kept my notes when I moved. I know one of the Allendorfer and Oakley books from the 1960s -- Fundamentals of Freshman Mathematics, maybe, or Principles of Mathematics -- had a couple of chapters on it. This was during the "New Math" era when abstraction was heavily pushed. I inherited a large collection of books, including these, and was skimming them and very surprised to see that included. Unfortunately, some of my more esoteric mathematics books, including these, are still boxed up after a recent move. If I can figure out what box it was in (and remember to update) I'll share it here. These are some very good books for future mathematicians and used copies are usually available on amazon. Another interesting book for a first exposure would be Carter's Visual Group Theory. This one works very hard at building intuition for this subject that is often presented so abstractly that not only can you not see the forest for the trees, but you cannot even see the trees for the leaves. You can preview the first couple of chapters here: http://www.mathcs.emory.edu/~dzb/teaching/421Fall2014/VGT-Ch-1-2.pdf While I'm thinking about it, another book that I should have added to my earlier post would be Weissman's Illustrated Number Theory. Again, there are a tremendous number of worked examples, and number theory is something that is very amenable to dabbling. I should also have mentioned David Burton's Elementary Number theory, which I used myself for self-study and found incredibly approachable. I had (at that point) had calc 1-3, linear, diffeq, and was taking discrete math. ETA: I am now thoroughly distracted from the test I was supposed to be writing because this is much more interesting ? I just stumbled across this book -- https://www.amazon.com/Ingenuity-Mathematics-Anneli-Mathematical-Library/dp/0883856239/ref=wl_mb_wl_huc_mrai_1_dp?ie=UTF8&pd_rd_i=0883856239&pd_rd_r=HWXQTYQE9Z3QV2WCZJXP&pd_rd_w=vusuY&pd_rd_wg=1D9Jc I have absolutely no experience with it, but the reviews are great, the price is not expensive, and it looks like it would be a near-exact fit for "dabbling".

Another popular choice is this one (that my current university uses- I find it very readable, but I may be out of touch ? ) https://www.valorebooks.com/textbooks/abstract-algebra-an-introduction-3rd-edition-3rd-edition/9781111569624?gclid=Cj0KCQiAoJrfBRC0ARIsANqkS_7Sg9k9AtPHGGrTFDnorh1uOztY81eAA5QJMMNqkYNFx0crNKWQIhAaAvUrEALw_wcB&gclsrc=aw.ds Edited November 10, 2018 by 4KookieKids 1 Share this post Link to post Share on other sites

Do you happen to have any notes or blog posts detailing your boys' math journey? I'd love to learn from your experience. Very curious as to when they started, what curricula/books you used, what material got covered when (e.g., 3rd and 4th grade in one year, etc), daily math routine, participation in any math enrichment/competitions outside the home, etc. You will now have so much time to cover other exciting subjects before the boys leave home! Great work! Sorry, I didn't mean to blow you off. Would you rather know what I did, or what I'd do if I had a do-over? General guidelines to use when accelerating young NT kids 0) Know your child(ren) above all else. Do what it takes to inspire your kids to feel confident, engaged and interested by mathematics. 1) Define your target. Devise a way to hit it. 2) Be the boss and own that role. You, not the kids, are in charge of programs goals and objectives. 3) Prioritize building the kids confidence and competency in the basics, over adding in rigor or challenge prematurely. 4) "Learning Styles" are pseudo-science crock that commercial educators came up with to sell products. So pick or create the resources that can get you down the path that you want to travel, but don't waste a ton of time and energy obsessing or trying to cater to a perceived learning styles in little kids. Little kids just learn. "Hands on" kids don't ignore the parts of the world that they can't touch, (or they wouldn't know how to speak) "Auditory" kids don't remain baffled about things that they can only see or they'd be stymied by a game of hide and seek. 5) The teacher has to put in the work. If you aren't working 3x harder than your kid, you're asking too much of the kids--you're likely going to burn them out. --Note:I'm 100% against programs that are "independent" for the kids and "easy" for the parent/teacher. If your kid is 12 or under, they need your supervision, guidance and attention. Period. 6) Only use intelligently designed drills, that are scheduled regularly and completed in a productively. 7) Be present and proactive in your kids learning. 8) If you have to choose between challenging young kids, or building their foundation--chose the foundation. 9) Do not sacrifice your kids sense of accomplishment or confidence in mathematics on the alter of rigor. It is easy to challenge kids on a topic that they are rock solid and super confident with. At that point, the challenging problems enhance their understanding, not call it into question and make them doubt. 2 Share this post Link to post Share on other sites

It does look like a good fit. Its on the short-list. 1 Share this post Link to post Share on other sites

This one works very hard at building intuition for this subject that is often presented so abstractly that not only can you not see the forest for the trees, but you cannot even see the trees for the leaves. You can preview the first couple of chapters here: http://www.mathcs.emory.edu/~dzb/teaching/421Fall2014/VGT-Ch-1-2.pdf While I'm thinking about it, another book that I should have added to my earlier post would be Weissman's Illustrated Number Theory. Again, there are a tremendous number of worked examples, and number theory is something that is very amenable to dabbling. Wow, Kiana these both look really fantastic. If I'm not careful you're going to bankrupt me! I've been looking at all of the books you recommended and am refiguring the budget >_<. I'm over here wondering if they can do without the Spanish tutor for a couple of weeks... I kept saying that I didn't want anything for the holidays, but I'll have to change that and tell people that I want an Amazon Giftcard. ? 2 Share this post Link to post Share on other sites

Gil 6,313 Report post Posted November 12, 2018 Our tentative Booklist for next year includes Visual Group Theory An Illustrated Theory of Numbers A Gentle Introduction to the American Invitational Mathematics Exam Life of Fred: Five Days of Upper Division Math Random back issues of College Mathematics Journal and MAA Focus, as they seem most accessible and suitable to our purposes and can be bought off eBay I'd been starting to feel stuck between the rock of rehashing stuff we've seen and the hardplace of stuff that's way over our heads, so I'm excited that these books can breath some new life into our math-time. I like that these books are playful, visually appealing and seem easy to read/follow. Its expensive, but worth it to have books that draw them in and hold their interest. 7 Share this post Link to post Share on other sites

How a ball flies, how a car drives around a curve, how it stops, how the Earth revolves around the sun, ,why there are seasons and tides, how your computer and your stereo work, how your cells let the sodium and potassium ions in and out, how your brain tells your foot to move, how your eye sees, how a telescope works... how is that "niche" and doesn't reach everything? Every object, every organism, every cell and cell organelle, every planet and every elementary particle is subject to the laws of physics. ETA: I would not stop math. I would seek out resources to learn math off the beaten path. Have you completed AoPS' number theory and counting&probability? Great topics, books written to the student so that no outside instructor is necessary. This. I was a little floored by the statement too. Every science discipline is basically just a spinoff indepth topic of physics. Maybe if you think of physics as the programming code of the universe you could learn to love it more 😋 Share this post Link to post Share on other sites
