Sooooo frustrating! Sorry kiddo, even though dad has an MBA, I just can’t seem to help you with your 8th grade math... Unfortunately Common Core makes no Common Sense to me.

Who the hell thought this math was better, and mandated it needed be taught to the kids?

I'm thankful that I grew up in a time where they made us do it the old-fashioned way. This method seems convoluted and I don't see how it's helping kids actually do the math any easier than we did. And what's wrong with memorizing the multiplication tables?! Anyone who's had to do that can quickly do it in their head instead of having to break out their scientific calculators. :glare:

:thumbs_up: Here here!

I guess I need to throw my math flash cards in the trash as they apparently now are obsolete... like me.

Hm. It looks as though they're offering it as one method, not necessarily the method, but I don't know that for sure.

Me, I did it in my head in about two seconds flat because taking away 25 gets you to 300, there's 13 left on the 38 you're subtracting out, and 13 from 300 is 287. But although that's easy for me in my head, I'm not sure that every other person would like it.

Beloved Daughter-In-Law is actually a math teacher in one of state's highest-rated school district (ours). I'm going to ask her about all this.

The time it took me to figure out the nearest 10 number I could have solved a page of subtraction the "old Fashion" way. Now I know why I retired from teaching!
I may not remember why I entered a room, but I can roll off the times tables with ease. It never leave the brain once memorized.
And-- a phrase which continues to be well spoken-- the world moved on!

It's not helping the kids on their test scores, either. Was just an article in the paper not too long ago that the scores in the county are down along with national average. Why stick with it then?

Evan started jr high this year, and it doesn't seem to be using common core, he is having a much easier time in math and has commented about how he loves his teacher's way of doing math. It is kind of humorous, because it is the way we all learned...but it is also sad because what exactly did he take away from math the last few years? Nothing.

I also read recently that the way it was built in, at least in Wyoming, means we're stuck with it for a few more years before maybe getting rid of it, cannot review it until it has been in use for 5 years.

Math needs to make sense. It's easier to understand something that makes sense rather than memorize steps that don't make much sense. A student who doesn't understand what and why the steps work will not do well in math. The old math based on multiples of ten makes a lot more sense than newer teaching methods.

I was teaching a 7th grade math class. My students could not work the problems. We were at the board working on one and I simply could not figure out the method or examples they showed me. I showed them how I was taught and we worked out the problems. Correctly. A passing math teacher looked in on me and saw the work on the board, promptly erased the work and instructed me NOT to show that method. Even though the students could understand my (old-fashion) manner. Crud.

Peace.
(BTW-none of the middle school or high school students I teach know their multiplication tables. In fact, when I ask they have no idea what I'm talking about.)

I had a similar experience. One of my clerks learned new math in school. She couldn't make change for a dollar :( I had to untrain her in new math and teach her old math. She understood old math just fine... once I convinced her to forget about everything she'd learned about new math.

Thank you.

I lived at the math lab working on algebra with Sister I-went-to-school-with-Moses. I felt like a chimp working on problems in memorized steps. I could do step 1,2,3, etc. I had no idea what the he11 I was doing so I couldn't *see* my mistakes. Sister explained forwards, backwards and sideways until the light started to brighten. :icon_idea: Yay! I UNDERSTOOD what I was doing. It was awesome! (I aced the class.)

Peace.

I struggle - my boy is in the last year of junior school. All of a sudden we had a meeting to discuss the school now doing calculations the way I USED to do at school, instead of the ridiculous long winded, over complicated way they've been learning. I was awful at maths, failed my GCSE 3 times, and never passed it. Now I'm almost phobic about it.

ME TOO! I passed, but I don't know how I did it and I did it with Bs. The phobia, I totally have a phobia about math and almost want to cry about it. I have to be honest, I do cry about anything beyond the basics. Got the basics down.But the rest? fuhgeddaboudit! A friend of my son's teaches math and he also tutors at the local university. I told him that one day I would hire him to teach me math (facing a fear) and I asked him, "how would you respond if an old woman started crying in front of you, because I will." I think I scared him.
