New Math

[3fifty7]

I just finished a night of new 3rd grade math and there were a couple moments of "I don't know what the hell they are talking about".
In the beginning basic addition, subtraction and multiplication IMO should be memorized to the point of second nature.
Checking work by reverse actions then needs to be implemented.
Place value and regrouping ect should then be taught to help further learning.

Sir, we don't need any logic or common thinking in common core.

I literally just finished helping my kindergartener do her math homework, and shes going take a bath.

I don't see what the big deal is with common core. I'm not a teacher and I'm not related to anybody who is, and I make it a point not to get super- political, but from what I can tell so far they're just teaching kids to find more than one way to solve problems. I mean come on, guys- right now I have a device in my pocket that I can use to access the entire sum of human knowledge within seconds. Yet I work with people that can't figure out how to format a .xlsx file. Maybe it's actually time to think about teaching our kids to be good at solving problems instead of memorizing charts.

Again, I couldn't care less about whatever the politics of the thing are, but from the outside looking in, it sorta looks like a step in the right direction...

Hrmmmm, if by more than one way you mean considering anything other than what they tell you is wrong... yup. And you should care about the politics, you don't have to be super political to want to understand whom is taking a front seat in educating your child.

I've been doing math like this for years! Didn't know this was the common core method. Just makes it easier and faster to do math in your head than the old way of "cross out the 2, make it a 1, carry the 1 to the 5 to make 15, now subtract 8 - carry the answer (7) down below the line in the ones place. Cross out the 3 make it a 2, carry a 1 to the tens place to make 11 now subtract 3 -carry the 8 below the line in the tens place. Now subtract an imaginary 0 from the number that is now a 2 in the hundreds place above and write that below the line in the hundreds place. Answer is 287"

Whew, so glad the"old" way was so much easier and to the point.

I'm with you on this. It's seems they've just written out how most mental math is performed. I've heard lots of complaints about common core that seem to be legitimate, but this doesn't seem like a real problem.

There's nothing wrong with teaching other ways, but they are just barely skimming the basic fundamentals and not building a solid foundation.

The issues with implementation not withstanding, the point of this is to teach kids HOW to think versus WHAT to think. The problem with the old way is as soon as the information people have been taught doesn't solve the problem many have no idea how to simply think it through.

Just waiting to see how common core tackles a quadratic equation. Or Algebra.

Its another big government issue that the liberals love. Bobby Jideal agreed to it at first for out state but then said he didn't want it in our state. It was supposed to be used so that every state was teaching the same curriculum to the students. It was never meant to be used as a teaching procedure. Its another reason I put my child in private schools.

how to do math today:

and to think that when I did this once upon a time, i got accused of cheating and received an F. I was just ahead of my time.

 

[whodat247]

They are making math way harder and longer than it needs to be for kids. This is insane.

math is quickly becoming irrelevant ala technology. I think in our lifetime we will see a dozen or so traditional classes become moot.

Foreign language, simple to moderate mathematics, grammar, etc to begin the list. I read somewhere that the next "latin" will be "manuscript", ie; nothing written by hand anymore.

They're teaching them different methods to solve problems. If the kid is supposed to be learning a particular method, and uses a different one, I can see how they would get a bad grade on that one particular test. And I couldn't care less who my kid's teacher voted for in the last election.

The private school my daughter is in has been using common core for over a decade. They have a pretty darn good record. And none of it has to do with who the governor or the president is. It just makes sense...

Imagine that. We probably should go back to memorizing multiplication charts. Who would DARE to teach our children to be successful citizens in 20 years when they'll be in the work force instead of when we entered it????

Exactly this.

IMO, advanced mathematics and foreign language should not be required. High Schools should have elective courses, including: Advanced Mathematics, Foreign Languages, Trade Courses, and Higher Level Literature Courses. It can be argued that America has no national language, but I don't think I'll need to break out my Latin skills to help the old lady at the stop and rob.

If you break out a translate app it doesn't matter what language she speaks - including latin. The only valid reason to pay 500 bucks to rosetta stone is if you're traveling overseas and need to hit on chicks.

I completely agree. Unfortunately, a large percentage of society doesn't understand how to access tools like that. I know of a few people that work on a computer daily and it takes them 15 minutes to one finger type a sentence.

Exactly this.

So that is why the cashiers can't make change if they enter the wrong amount tendered, or hit the clear button before seeing the number.

I spent 2 days going over this stuff with my 2nd grader and she broke down and cried the second night because she couldn't understand it. I finally taught her the way I know it and within a half an hour she was adding and subtracting 4 and 5 digit numbers with carrying and borrowing. I have an excellent understanding of math (wrapping up a bachelors in engineering) and have all sorts of methods I use to help myself with things but I learned the basics first and figured out my own ways to make solving easier. I can appreciate teaching alternate methods to figure problems out but some of these problems take me a minute to grasp what they are even asking, for my daughter it has made her dread doing her math homework.

OK, don't want to start any problems, but you can take your common sense and shove it... Just joking totally agree with you.
