Ugh.

So, this person doesn't like the Everyday Math curriculum, nor... some other math series.

And she might have a very good point about that - the nieces' school went off Everyday Math because the teachers said they jumped around too much and it was confusing the kids. This is an opinion I can trust - it makes sense to me, and the people saying it presumably know what they're talking about.

Unfortunately, I can't trust this presenter's opinion. Her argument against these two curricula aren't "Kids find them confusing" or "I don't think they're teaching math" but "They aren't teaching math the way I learned it, and I don't understand how they're teaching it, so it's wrong wrong wrong!" So, of course, she demonstrates these methods... and it's obvious to me that she's clearly taking the slowest, most round-about method of doing this in order to prove her point. But she *doesn't* prove it.

The lattice method? That one that everybody derides as "who invented this"? I'd guess that if you know what you're doing and aren't unfamiliar with it (and no, "parents aren't familiar with other methods" is not a good reason to only do what you've always done) it's just about as fast as the more common method. (And it's not exactly new. A method that's been around since the 13th century CE and that appears in the very first printed arithmetic book? I'd say it has some staying power.) She says that her preferred method of division is "the most efficient" method, but it's only, in my view, more efficient when writing with pencil on paper. If you have to work something out in your head? Reasoning - which she thinks is just wrong wrong wrong - is the way to go, and, indeed, is how I do most of my math... and which is why, unlike most people I know, I never *do* reach for a calculator or a pad of paper if I come across a necessary math problem in the course of my day. (And nobody ever yet has explained to me how you can use long division to divide, say, 31 into 2000. Not without memorizing the 31 times table, that is....)

It may be that these two programs aren't teaching kids well. In fact, I've heard a lot of bad stuff about Everyday Math specifically, so I'm inclined to believe that. But unfortunately, she let the facts lie to the side while she spoke about her opinion that one form of problem solving is superior - so much that the others shouldn't be taught.

I was so annoyed by that detail that when she said what really should have been her shocker - a quote from the Everyday Math teacher's guide stating that of course, calculators are readily accessible (and so not all algorithms for basic arithmetic need to be mastered) - I started wondering why she didn't answer that important question - why IS it necessary to know how to do basic calculation? (Judging from the comments, most people don't know. I read a lot of "People who do this method would fail all their tests!!!" or "How can you show math on a test using that method? You wouldn't get any credit!!!!" or "If you don't learn the right method, how can you compete in college?" or "This is why students in other countries do better than our students" but not once did I see a comment explaining when math comes up in day to day life and it's better to use THIS method over THAT method. I find this much more disturbing than the original comment about calculators!)

And, really, thinking it through, I can think of a few ways to justify the calculator comment anyway. One person in the comments went "Well, math is easy when you strip it of the clutter, all those word problems". But who is better at math? The child who can tell you that 12 x 12 is 144 and that 6 x 12 is 72, but has no idea why he's memorized that or that the numbers exist outside of the book? Or the one who needs to use a calculator but who can work out all the right steps to find out how much paint you need to paint the walls (but not the doors or windows) of a given room? (All while the first child absentmindedly fills the room up with paint!)

Actually, what's even worse than the fact that the commenters didn't seem to know what we use math for is the fact that few of them realized she was selling something. They took her deliberately confused approach to these "alternative techniques" and assumed that meant that nobody can do any form of calculation using them. (I'm doubtful many of them understand why the standard algorithms work, to be honest, but I suspect none of them understands why it matters if they understand or not.)

Here's somebody's reply to it.
And here's part two!

Apparently he's since found a copy of (some of) the books to review, so I'm going to look that up to see what he says. It really irked me watching the first video (the firstest one, the one at the top) she talks about how at the end of the 4th grade curriculum there's a "world tour" project and "Where's the math?" Well, I don't know where the math is, honey, you're the one holding the book, you tell us! Off the top of my head I can think of any number of ways applied mathematics could go into planning a world tour, but without a copy of the book I can't tell you if they did that well or flopped miserably. Her implication, of course, was that connecting math to any other subject (such as geography or social studies) was wrong wrong wrong! because, after all, it's not how SHE was taught. (And maybe there IS no math there, I wouldn't know, but I'm interested in seeing another opinion because that first video was so obnoxious.)
