As you may know if you follow me on Facebook, I pretty much hate, with a capital H-A-T-E, this “new common core” math being taught. Every day it’s a massive struggle for Chris and me, him with a Masters Degree and myself with a Bachelors, to teach 3rd grade homework to our daughter.

Putting aside that we work for hours past an *already* 8 hour school day, ignoring that we are provided no text books to learn about the material, and sweeping under the rug that they send home homework on things they have yet to even teach yet, we are doing our best.

But we are lost.

**LOST. **

And I am a bit angry to tell you the truth.

Today was just another example of “fuzzy” math.

This is on Charlotte’s homework:

All her problems have to be done this way.

Under what math EVER would 291 be “estimated” or “rounded off” to 200? Am I missing something? And this is the example for her to base all her other math homework on.

I can tell you that if I estimated or rounded off my bills from $291 to $200, I would get a notice of an unpaid bill. I am not sure my mortgage or car payment would agree with that.

And let’s jump to the answer. The estimated sum ‘500’ is *considered reasonable* with ‘645’?

Is 5 million the same as 6.5 million? Ask an accountant that. Ask a corporation that.

I can’t help but wanting to refuse to teach Charlotte something that I find completely and utterly wrong.

The more I look at people’s reactions to Common Core math problems, the more I am convinced that these adults lack basic understanding in elementary mathematical notions and concepts. And frankly, to those of us who have an understanding of mathematics, you are making fools of yourselves.

First of all, this is a practice problem in a technique. Mathematics training, at all levels including the most advanced, has been doing this for ever. Practice problems are often simplified illustrations of a concept, given for learning purposes. The goal, is for the student to grasp the underlying principle. It is not necessary that the problem reflect anything immediately useful.

What I find most striking about people who criticize common core by picking on math problem examples, is not even that they are ignorant of the elementary mathematical concepts being illustrated. It is the arrogance with which they proclaim their ignorance as knowledge. People, the problem isn’t with the Common Core … it’s with you and your level of understanding… and the fact that most of these elementary concepts are lost on you.

However, for all of those too dull witted to be unable to contrive a example for this particular problem where this estimation technique would be both useful and valid, let me do it for you — A ballroom has a capacity of 700 people. We are having a party where two classes are invited. The first has around 354 students and the other no more than 291 students. Is the room large enough? Using the estimation technique above, we estimate 500. The real number has to be within 200 of that estimate (why?), so yes, the room is large enough.

The problem is you. Not Common Core.

This reply is the stupidest ever! Its insulting. The way we learned math when we were kids worked for us and now they are doing it a longer harder way. I think your smarter if you can do math in your head rather than have to write out a huge problem that can be done faster the old way. Common core sucks and I think you suck too.

What an imbecile! The problem is people lime you who don’t care about the correct answer. The correct answer is not an estimation. I am completely with Trisha. According to your mentality, 1 + 1 = Could be 1 or three because the estimation is close. You are a nut job.

Common core is terrible. There is no reason for 6th graders to cite text evidence on a classic fiction story.

I HATE common core! How can I help my 6th graders with homework when I don’t understand it myself??!! My son asks his teacher for help and she tells him to try and figure it out by himself! They have no books with references or examples for educated parents to look at. My son use to get great grades in math, now he gets frustrated and feels stupid because he can’t solve simple problems that should take a few steps instead of 30 steps. Common core is the most ridiculous thing! I don’t understand how my 11 year old is suppose to learn something when there is no one or no book to help him! It’s incredibly frustrating and and demeaning. Teachers expect these kids to understand the concept they day they teach it and then to move on to the next concept, when they can’t understand any of it.

My daughter and I struggle through her homework, which calls for diagrammatic representation, explanations, and justifications to explain the most basic concepts. Did we really pay millions of dollars for this? And the educators are now blaming the schools, the teachers, & (are you kidding me), the parents! Do the parents need to go to school again to help their kids with the homework?

I 100% agree with you. As for the person commenting without kids – his opinion is null and void!!! I have no idea how to teach my daughter how to do her 4th grade homework. I don’t see how this is going to help her in the real world – you cannot estimate that the pineapple in the grocery store is $1.00 if the price tag is $1.69. Sorry. They wouldn’t sell it to you.

Ummm, have you read the Common Core Standard (CC)? So I just saw this example and yes, I agree, it is wonky. So then I did a little research (very little) and read the entire 3rd grade CC. It doesn’t take long, it’s just some achievement standards. So all these ridiculous examples I keep seeing friends posting or reposting have nothing to do with common core and everything to do with your state implementation, the teachers, and probably most importantly, whoever is writing the textbooks. I don’t have kids, so I really don’t care all that much. But I do not like misinformation so guess what, the common core is not the problem. Read it then point your laser cats at the right target.

Since the books have this stamped on them….. (and this came directly out of my daughters desk)

I can see where people would be confused but it seems the makers/authors of the textbooks are to blame, not the standards. What does the inside cover show I wonder. And seriously, you should read the common core guidelines if you haven’t. If everybody start directing the problems at the right source, maybe something can be done.
