I don't think anyone here has said not to memorize for math. What has been said is that it should supplement actually understanding it so that when you move on to harder things and your memorized square peg doesn't fit into a polygon shaped hole, you're not lost.

And I'm saying you should be able to memorize it just based on use and familiarity.

Allowing students to actually be taught math instead of just memorization

If I just now broke this down into 79x10 + 80x3 - 3 did I do common core? B/c that's the way that made sense to me.

80x10=800

80x3=240

800+240=1040

1040-13=1027



79x13=1027

does that matter?


For your current use? No

If you're trying to teach Math, yes

Awesome. Irrelevant, but I enjoyed your story.

I'll choose the method that let's the kids gain an understanding instead of just throwing up an answer. Memorization will come with repetition

The largest problem I've seen and been involved with at the school board and curriculum level is how much of it never took into count the age appropriateness of the children being taught. No one in development ever took into account the level of the learners and thus never designed it on step building based on the development mentally of the learners. This is most apparent in the math portion of the elementary curriculum.



Gee, I wonder how all those PhD educators missed that.

well that sucks. i guess i'm done.


on a side note, had i been taking my Fluids final, and i made this mistake on one of the problems, zero points would have been taken off for that error, assuming my final answer was only wrong b/c of this error.


I'll tell my boss that when something I designed failed because I transposed a number or did basic math wrong costing my company hundreds of thousands of dollars. My fluids teacher would have given me full credit!

Doesn't take a genius to figure this out without a calculator or pencil/paper.


Never said it did...it wasn't supposed to be some monumentally difficult mental exercise. The point is when a student really understands mathematics they are developing algorithms to efficiently solve problems like that without the use of calculators or pencil to paper computation. Over the years they continue to develop that fluency with numbers and extend it to more complicated topics.

If someone wants me to figure out 9x8, I can't see one fathomable reason why I'd need to do all that just to arrive at the same answer.


It's about teaching an methodology. It might not be the simplest method to solve 8x9 but what if you were given the problem of 168x99? I can do 800-168 in my head to get the answer of 16632 much quicker than having to write it out on a piece of paper. I can see the logic behind common core trying to get our students to think more abstractly. I can't say the curriculum is implemented correctly of even if our current teachers have abstract thinking ability yo teach this type of curriculum.

Common core is meant to give less intelligent kids the same understanding of math that smart kids have. If you give a word problem to both sets of kids, the dumb kids might tell you the answer, but they won't actually understand what it means. They don't have a tangible understanding of what math means. Common core is a way of trying to explain that to them. From what I've seen, it's still way over their heads.

The other use of common core is the 'common' aspect of it. Everyone has to use it, no choice in the matter. It's a way for government to standardize education and run it like an assembly line. Ideally you teach every kid this way and it works. But that's not how education works. Different kids need to learn in different ways, and the best way to do that is more individualized teaching. Smaller class sizes with more attention for each student and more creative teachers that can change their lesson plans to fit the needs of their students is the best way to teach

Maybe because they did not consult any child psychologist.... My uncle has a PhD in physics and teaches math at a college level. He is one of the most clueless individuals I know. Sure he's smart but he has zero common sense and I can't believe he's educating anyone.

I wish Common Core was around when I was in school and I learned math that way. I am awful at math and cannot do it well in my head. The math I do know is generally just memorization or tricks I do to come out to the right answer.

My dad is naturally better with math and the way he describes it sounds JUST like common core. He understands the relation of numbers and can calculate things fairly quickly. I, on the other hand, struggle with even calculating change or giving a tip at a restaurant. I default to 20% just so it's easier.

Years ago I developed my own technique for doing calculations in my head and I was pleasantly surprised to see that common care math uses pretty much the same method. I can understand why this would be greek to someone who needs a pencil and paper but it's a vastly more efficient way of doing it.

I'm not disputing the ability to learn math as it is presented. I've viewed the material and have had no problems and neither has the one child I have right now in school. That still does not change the fact little ones need concrete structure at this time in their development. As well a step building process and not just here is the material as it is laid out without building the groundwork and good luck figuring it out. Elementary is where the greatest gaps in the curriculum really stand out. Children think differently than middle schoolers and adult. They are concrete and not abstract. It is the same reason why there are not as many issues with high schoolers struggling. They are able to think abstractly.

I know my kids 1st grade math homework is beyond ridiculous.

Block 10s are idiotic and it takes 3-4 steps to do what could easily be done in 1 or 2.

The more I learn about it, the more I think it will make alot more sense when people get older and are doing rough math in their head. When I'm at work and hear figures that I need to multiply I'll constantly do something similar to common core where I break them into small easy figures, multiply them and then add them.

Having said that, seems like it would take forever to do it by hand, but then again do kids do anything by hand anymore these days? Except fingerbang their teachers I guess.

I'll bet at least 80% of you are misinformed.



My teacher friends claim that Common Core is actually just the set of standards of what they need to teach and the kids need to learn, not actually how they go about teaching it. All the weirdo math work bullshite is actually not supposed to be common core according to my teacher friends.
