I don't have kids but I have a nephew I'm quite involved with. These methods, to me, are really foreign, but I can see them working. They make sense, once you give them a bit of thought.

There is a DUer here who has admitted having to use Google search to figure out WTF is going on, but she is glad to do it, because she herself has had difficulty learning stuff and she wants her daughters to succeed.

I think 99% of the backlash is from parents who don't want to go that extra mile to figure out what the teachers are teaching (who, btw, 99% of the time, are implementing things themselves, not by some evil corporate hierarchy). It's so disappointing and saddening because I think the new methods help children, and don't hinder them.

I'll relate a personal issue I had with algorithmic addition / subtraction. It was so difficult for me to understand the inverse relationship between addition and subtraction. It literally made me fail algebra. I didn't get it. I was so confused and lost. "New math" tries to get rid of that algorithmic methodology and teach kids "number sense."

14-4-2? It is sort of how I do it in my head. bettyellen Nov 2014 #1

Seriously??? msanthrope Nov 2014 #2

I am so glad my kids are out of school B2G Nov 2014 #124

I guess I'd choose the "14-4-2", but I don't know what the petronius Nov 2014 #3

Same here, I have no idea what that's all about. arcane1 Nov 2014 #6

The kids call them "tens boxes" Codeine Nov 2014 #94

Hmmm. Interesting. I've been reading your comments throughout the thread and they make sense stevenleser Nov 2014 #188

It's giving the answer. joshcryer Nov 2014 #47

14-4-2 is how I do it. uppityperson Nov 2014 #4

Same here. LuvNewcastle Nov 2014 #12

I am with you .... make a ten. I take it the (14 - 4) makes the ten. = Tuesday Afternoon Nov 2014 #45

You would if you had been exposed to the lessons sammytko Nov 2014 #74

Yeah, that lack of context is where the "shock value" comes from. arcane1 Nov 2014 #123

The idea is to "make a 10" because it's easier to subtract from 10 than from a larger number. Why? demwing Nov 2014 #115

sort of like approximation? yurbud Nov 2014 #153

The only illustration that makes sense to me is the third box. RoverSuswade Nov 2014 #7

You have to fill in the bubble. The boxes all relate. madfloridian Nov 2014 #39

How do first grade minds work? joshcryer Nov 2014 #48

This isn't first grade math AgingAmerican Nov 2014 #140

14 - 4 - 2 ... because, 14 - 4 = 10, 10 - 2 = 8, = 14 - 6 = 8 n/t RKP5637 Nov 2014 #8

I get what they did here. Control-Z Nov 2014 #15

That is not correct syntax. Rex Nov 2014 #17

It is when you're taught that way. Codeine Nov 2014 #95

The question is worded oddly. Jenoch Nov 2014 #18

This is simple math. Codeine Nov 2014 #106

You are correct Jenoch Nov 2014 #121

I frequently do the same. Jenoch Nov 2014 #189

This IS simple math. 14-6! Except they are teaching a specific way to calculate inside one's head. Threedifferentones Nov 2014 #180

The question is the key - "Which way to make a ten to solve..." csziggy Nov 2014 #19

The whole point seems to be to slow them down Wella Nov 2014 #55

Yeah, I lost interest in math once they made me write down the steps csziggy Nov 2014 #56

I don't think it works for most people in general Wella Nov 2014 #58

It must be a success, then csziggy Nov 2014 #59

That's why so many of us are opposed to Common Core Wella Nov 2014 #60

And my experience was 55 years ago, long before Common Core or New Math! csziggy Nov 2014 #61

Tin foil hat, here, but I think that was deliberate Wella Nov 2014 #62

I'm starting to suspect that - the education my nieces and nephews got was bad csziggy Nov 2014 #64

Why put foreign in there, unless you have something against foreignors? Bandit Nov 2014 #79

Because if they are foreign, they can be much more abused than American citizens Wella Nov 2014 #135

Thank you. Rote memorization is the best way to get such small math facts in Nay Nov 2014 #68

It hasn't been taught this way. joshcryer Nov 2014 #50

Exactly. This codifies and teaches Codeine Nov 2014 #103

Wrong. A kid is going to be exposed to this for the first time, and learn the method. AtheistCrusader Nov 2014 #174

As an engineer who tutored many kids in my past U4ikLefty Nov 2014 #24

We have a high percentage of foreign born in our district, and that has always been my argument pnwmom Nov 2014 #28

Actually I agree, but they were excetional math students, better than many US-born kids. U4ikLefty Nov 2014 #31

Yes, after they have a command of the basic math skills pnwmom Nov 2014 #41

I'm currently in a mood about division and 4th grade math in general. glowing Nov 2014 #119

WHAT??????????????? I actually WAS one (English Lit here), and I say this "question" is BIZARRE. WinkyDink Nov 2014 #109

The question makes sense to kids taught Codeine Nov 2014 #113

I'm sure many things make sense to those "taught to understand." Scientology, e.g. The POINT, WinkyDink Nov 2014 #171

Children haven't changed. That's the problem. pnwmom Nov 2014 #46

Really? Because as a small child I would've just said "14 - 6 = 8." Simplicity itself. WinkyDink Nov 2014 #111

The way we learned math is equally weird, MineralMan Nov 2014 #96

Is he taught to draw a block of 10, and of 4, cross out the 4, and then draw another block of 10? muriel_volestrangler Nov 2014 #98

He probably did that twice. Codeine Nov 2014 #100

Having to draw it twice doesn't seem 'immediate' to me muriel_volestrangler Nov 2014 #105

I mean he used physical drawn-out tens-blocks Codeine Nov 2014 #110

What I mean is that the diagram in the question has 4 groups muriel_volestrangler Nov 2014 #120

I don't even understand the question. Smarmie Doofus Nov 2014 #128

The notion is that adding or subtracting to and from a "ten" is quicker and easier Codeine Nov 2014 #133

So added steps are preferable to just knowing the values? "14" isn't exactly the national budget. WinkyDink Nov 2014 #173
