I used to think I was half way decent at math. Now that I am helping my 7 year old, I am seeing problems I help him with marked wrong. I hate this new math.

Ugh. I remember some of that new math when my kids were little.
Some of it was utterly stupid.
I told my son not to do an assignment once and then went and had a nasty talk with the teacher. The problems were so simple you could just look at it and know the answer but the way they wanted him to solve them took a full page and fifteen minutes per problem.
I wasn?t raising any government workers. I don?t need my kids being taught the most inefficient way to solve a simple problem.
Dear K-12, undergrad, grad schools.
Just teach the damn normal math like:
Algebra, geometry, trigonometry, calculus,
Differential equation, linear algebra,complex variables,abstract algebra, partial differential equation crap!!
Do not teach us some alien andromeda galaxy math....
Confirms for me that teachers are way overpaid.
Predator (alien) arithmetic and numbers.

Ok, color me stupid. How is #7 wrong? 3 - 10 = -7
Without seeing the context of the math problem it's hard to see what they are pushing for, but every other example of "new math" that is being taught (even into highschool) is just mind numbingly stupid.
Your kid is right. .gov employee is wrong. I decode alien math all the time. Some of it takes months to figure out. I know a lot here think I am just telling fibs. Official .gov link below...

WTF? 7 = 10-3
I don't see what angle they could be reaching for that would make 7 = 3-10 true..
3 - 10 is -7
If you have 3 dollars and take away 10 dollars you are negative 7 dollars
No wonder the teachers are complaining about not being paid enough and they are broke. Since this is probably the way they balance their check book.[ROFL1]
That is some crazy Dr. John Nash stuff without meds.
My pt is.
Our math science and engineering is most likely far behind alien stuff. Why complicate our math and go backward?

This is a very basic problem.
A+B=C
Subtract B from both sides
A+B-B=C-B
A=C-B
It’s not rocket science, it’s not new math, it’s simply a wrong answer key.
If 10=7+3 then 10-3= Triangle!!!!
OP should send this to teacher and get the points back.Quote:

They don't ever balance their check books. They use their credit, or debit card to cover the checks written.Quote:

With our money.
I have sent one paper back before asking for clarification on another problem he missed. She didn't bother to respond. Parents are not allowed in the school still. It is difficult to deal with this over the phone. I agree, I thought 3-10=-7. I am wondering if we are the only ones who actually check our kids homework after the teacher checks it.
To be honest, do people still balance check books?
I haven't done that since online banking became a thing. I know what I have and I know what I spend. Every morning I review my account just to make sure all is right with previous days charges/debits/deposits. If all is well, I'm good.
Yep.. this.Quote:

I haven't balanced my checkbook in decades. I use the register to simply track the few checks I write. We do pretty much everything online.
In regard to the sloppy math instruction, I have to wonder if the 'new math' is an intentional distortion to keep people dependent on what other people tell them is the answer to *fill in the blank*. Instead of doing the math to be able to understand what "the science" actually means, listen to what the media tells you to conclude about *insert agenda item here*.
I'd take that answer sheet, slip it to the principal and ask HTH his staff passed basic instruction skills, that you were going to contact the school board and demand every teacher be able to demonstrate basic reading, writing, and arithmetic tests from a 1960s-era primer.
Nah. I?d just duplicate the problem without any ?corrections? and send it to the principal to solve. If he comes back with a normal, correct answer then tell him he is wrong. If he wants to debate then point him in the direction of the teacher so that he/she can explain it to the principal why his answer was wrong.Quote:

There may be some of that involved. After a couple decades dealing with "new maths" as a parent, I have determined that the new math techniques were developed as alternate solution methods for kids who struggle with the classical method. Then, in the wisdom of school administration, Fed education officials, whatever, ? it was determined that these new methods may make the few kids that need it to feel substandard, so to keep everyone feeling equal, we will require all kids to learn these methods. Then over time, additional new methods are found, expanding new math. Now, each kid has to master anywhere from 4 to 10 different ways to solve the same problem. This burns up so much time that the kids don't get to the more advanced topics and end up behind for the next year. Over focus on "inclusion" and "self esteem" is crippling our science programs.Quote:

Keep in mind, even though your kid was marked wrong, the bar has been lowered down to where they will still get a B or better unless they are having social issues. I have watched average grades continue to rise while required content has continued to drop. As long as kids grades are a reflection of teacher performance, this crap will continue.
I start to wonder what they teach in history then.
I assume
"We didn't land on the moon, the Soviet did with martians help."
More like, "White men landed on the moon, but you don't need to study this as it wont ever impact your life. Lets move on."Quote:

Any questions?
Women and Black Mathmaticians matter and contributed on that matter on a movie "Hidden Figures."Quote:

Hey, thanks for posting the clip from Hidden Figures.
I am inspired to watch it, now.
See if I can find it on Netflix, Prime Video, or Comcast On Demand
Old Math!
