BetterToRuleInHell posted:Apparently it does because the temperament of the replies so far are as if I insulted their mothers as well as questioned the math. It still seems odd that this particular method is somehow easier than simply writing out x-y=z, which itself is just a written expression than can be done in your head anyways. I don't think the point is necessarily that the number line method is "easier" or "faster" than the standard x-y=z (I mean, it obviously isn't) but by showing subtraction in the context of a number line, some of the underlying mechanics of math are exposed and hopefully in the process of learning those mechanics they can be tied into other concepts and principles. By then including a "write a letter" component, it gives the student a chance to work through what they've done and explain it to someone else, which is another way of reinforcing new material. That also gives more points of a failure I suppose, and it doesn't help if you have a father who dislikes encountering things that they can't understand when you ask them for help and then fails to properly do your homework for you.

Everyone ITT needs to watch this now. This is happening in my dinky appalachian state just like so many other states with rabidly right wing legislatures. This is new to us though. The Delegate featured is Mike Pushkin who is so awesome I wish I lived in his district. He's a working class dude (cab driver) and he doesn't mince his words. Stick it out to the end for an amazingly sick burn.

Math chat owns I find that the common core stuff seems to separate out those who learned how to get the answers out of math vs those who learned math, if that makes any sense. The former are the ones who complain about word problems and "I never use this". SumYungGui posted:One of the more awe inspiring things to realize about math, and something that would seriously never have happened to me if it weren't for one specific amazingly good teacher, is that at some point it transitions into what feels like learning a language, not learning math. There comes a point where things just click together and you realize you're not just memorizing another stupid pointless formula, you're figuring out the alphabet of an entirely different language that can show you some really mind-blowing things. Or basically this. That people can learn to get answers out of math isn't a problem, it lets then get the job done and ultimately that's what counts. But understanding math conceptually is so much easier, particularly in our modern digital world, where there are tons of machines that can do operations for you so the real skill is seeing how to put operations together because you speak the language of math. foobardog posted:Well the point isn't even to just teach one algorithm for doing this, but to teach many and be able to train students on generating their own through comparison. This particularly applies to programming. This is to the point as well, that understanding how operations link together conceptually is what you are really gaining here, not that 12*12=144. Like you never need to specifically drop the quadratic equation in day to day stuff, but the skills you learn in algebra class of "identify terms, find what is missing, rearrange components to get the missing value" is something everyone does every day instinctively now. If you want some real mind blowing stuff with math and concepts there is Godel Escher Bach. Which yeah is the one book every pseudo intellectual has read and claims explains everything, but it does that because it really does link together concepts in a mindblowing and revolutionarily different way that can change how you see the world. The catch is to not let it be just the one book you read and keep building on top of that. The MIT course on GEB is on YouTube btw, really helps add to it

I honestly dont see the need to switch from the old method. When I was in school if you wanted to learn math you had a ton of practice via homework and if that still stumped you you asked questions. What I'm more concerned about is the fact that I'm still running into people that are straight up illiterate in the year 2016. I know people that can handle trig and calc but cannot sign their own name or struggle to read a sentence.

I guess theres that lingering anxiety of your kids understanding something that you may never be able to that is responsible for a lot of push back against this sort of thing. More or less the same debate was going on in the 60s, when we introduced the "New Math" into schools. There was clear agreement that we needed to train scientists and engineers faster than the Red Menace could train theirs, and that the old methods of math weren't sufficient. In a truly brilliant move, California got Richard Feynman to join the board that was picking out their textbooks. He wrote an entire essay about it, but I've always thought this part was particularly relevant: Feynman posted:What is the best method to obtain the solution to a problem? The answer is, any way that works. So what we want in arithmetic textbooks is not to teach a particular way of doing every problem but, rather, to teach what the original problem is, and to leave a much greater freedom in obtaining the answer -- but, of course, no freedom as to what the right answer should be. That is to say, there may be several ways of adding 17 and 15 (or, rather, of obtaining the solution to the sum of 17 and 15) but there is only one correct answer. What I particularly enjoy about Common Core is that, fifty years later, they're finally taking his advice. It's less cool to see that the people who originally objected to the New Math now have grandchildren who are using the same arguments.

The Common Core math approach tries to apply a good set of ideas about problem solving to calculations so basic that they do not require any particular thought. 100+250 is not the best place to start with that stuff - they are taking a better approach, maybe, but to the same old dumb problems that students don't need to spend years masturbating over. edit: Feynman gets it - that mentality isn't failing a kid for not using a particular form of "show your work", conventional or Common Core.

Yeah, this has been the admitted downside of common core. They just replace having to do things with one algorithm with a few and mark things wrong when the current algorithm is not used. But that's a problem with over testing and the teachers themselves often not understanding it nor being given the time to do so.

I almost wonder if making earth-shattering changes in elementary math ed is even a productive idea to consider- there are a lot of structural obstacles to any changes there, that go beyond "mere politics". Elementary teachers are spread thinly over a broad range of subjects and did not study any of them in depth in college, and without changing either the structure of elementary school or of educator training (or both) we can't ask for a more advanced approach to mathematics. The traditional and terrible Algebra 1/Geometry/Algebra 2 classes might be a more productive place to start, because they are by and large taught by people with 4 year math degrees.

Ardlen posted:Remember the target audience for Common Core. While for someone old enough these calculations are basic and do not require any particular thought, for first or second graders these math problems can be quite difficult. Giving students additional tools to solve a problem does not invalidate the ones already in use, but it does help those who learn differently. Using pictures, number lines, or weights on a scale can make these problems visual or tactile and lead students to better understand and solve the problem. Remember that for any kids that are struggling, if they've got decent parents their parents are trying to help them with this stuff. If their parents can't help them because what they learned is very different, they've got a problem, as it's very possible that the teachers are overworked (or are just bad). Some of the criticism of Common Core is purely reactionary hogwash, but some of it is coming from parents whose kids aren't in the best schools, who have overworked teachers, and who also likely are working full-time or multiple part-time jobs and can't afford tutors nor do they have tons of time to relearn all of this, if they are capable of doing so in the first place. Common Core is a visible target for frustration with the state of public education.

Opposition to common core, from both the right and the left, is not really about the common core. The left tends to oppose it because they oppose standardized testing, which is valid, but standardized testing is going to exist with or without the common core. The right tends to oppose it because they oppose the Federal government doing anything, and they might make are children learn about racism.

I think my biggest objection to it is that it can be easily mutated into a new and unconventional form of "drill and kill for the big test". A problem with any of the STEM pushes these days really. I understand that we want kids who can write proofs and solve problems, that's a great goal for a mathematics curriculum and dovetails really nicely with CS education as well, but what I've seen of Common Core math doesn't go far enough in that direction, it's politically-expensive window dressing.
