Common core math looks like a smart way to do it

On paper

But if I'm adding numbers in my head I'm not juggling a stack of 5 numbers and equations in my head

32-12 should be an immediate reaction, not a process

With the added benefit that you can easily do it in your head.

Because 34+13 is so hard.

I wasn't aware that math education in the US never goes beyond subtraction of two-digit numbers. (I'm assuming your + was a typo)

what about 699 + 12,284? I can tell you a method that gets you the answer of 12,983 much faster than doing it out by hand

Round up to 700

12,284+700=12,984 then subtract the excess 1

Too easy

correct, and this is the kind of thing you do in the common core. learn properties about numbers to do the math mentally sometimes instead of just jumping to the algorithm. this is useful.

Why is speed a factor? Shaving a few seconds off is not really necessary in most cases.

you don't know why speed is a factor in today's society?

also, the main point is that you learn properties of the numbers. if you just learned "how to add the numbers", you don't need to develop such an understanding

Learning how to do the same thing many different ways will increase the underlying understanding you have about the process. That's kind of obvious tbh.

Furthermore, mathematics is a very vertical subject. As you progress further and further, it's extremely important not only that you've operationalized what you were taught before, but also that you understand it properly. If not, math becomes super hard, because you need to memorize a lot of formulae and algorithms that you don't understand.
And in the society of today and tomorrow, the demand for engineers gets larger and larger, so strong math skills will be more relevant than ever. Not to mention the fact that a strong grasp on statistics is useful for literally every citizen.

I don't think most people would have a problem with Common Core if it were explained to them correctly the first time around. It becomes almost a political identity thing after that, so almost no reason to try to convince people.

so then learning say, that method, would help develop such a skill for some people. doing so in a number of contexts throughout math would develop that further, and place a value in thinking smart by understanding how something works. that kind of skill is useful in many contexts in life.

oh there's no point for many people. it should be obvious in this political climate that many people are happy to stick with what the currently believe and don't care to learn about the other sides' perspective and what might be valid from what they are saying. this is an area where i don't think there is any chance of climate change in the near future.

little kids should just go through Euclids Elements and convince themselves of each proof and then be tested on reconstructing them then they should be taught formal symbolic logic and spend highschool reconstructing arithmetic according to Russel and Whitehead's Principia Mathematica. Think of how much better this world would be.


lmfao this! great post !!


teaching math in this way (beginning with very formal mathematics) was attempted decades ago, and was not very successful. if you actually studied math education instead of making trolling posts like this, you'd know that this was attempted and shown to not actually be a good idea.

ive seen so many things out of context already enough to know that perhaps the context was pretty fucking spot on


how many things have you seen? and how many teachers and students are using the CC every day? you realize what you've seen, even if it was 1000 (it wasn't), is a very carefully selected sample from millions of math problems done every day.

Honestly the hardest part about teaching math is just everyone's shit attitude toward it.

Parent: "Lol I sucked at math in school and I obviously turned out fine so my kid's grade is whatever in that class"

Kid: "I've never been good at math so I'm not gonna start trying now"

Etc

typically the problems you see circulating on social media are taken out of context. more to the point, the issue isn't with common core but how some teachers attempt to dash out the standards
the convoluted shit you're referring to isn't the fault of common core any more than it's the Colonel's fault your fried chicken had a rat in it

This


in the common core, you learn to do mental math, and the standard algorithm.

ultimately, you DO do it in your head. there's a process that you go through AS YOU ARE LEARNING IT. it is not meant to be the way you always do it. it's about developing conceptual understanding as you develop the procedural fluency, and then you will ultimately use the standard algorithms / do it mentally as you would "normally"

this is 4 examples out of how many teachers / schools / students? also this is a set of problems taken out of the context of the entire curriculum and tells you nothing about where these fit into the entire process of teaching this content. study the entire curriculum and then come back with an analysis of its pros and cons

This is what we're talking about when we say "taken out of context"
for instance, in these two images the goal for the student is obviously to break down the numbers into the closest 10 so as to do mental math easier
this is how any adult who is halfway decent at math should be doing. the point here is to help those kids who struggle to do mental math see a quick way in doing it. it's not expected for you to always do math this way, it's building fundamentals the same way you'll never in real life need to spell "disambiguation" without having access to a spell checker, but they make you learn it in elementary school

27_Sandman_40 posted...

InPAbRl_d


using context clues, we can assume that estimation was the point of the lesson and the student didn't follow the directions. it's not honest to cut off any directions that the worksheet possibly had given that this is question number #9

J2cr3MI_d


a quick google search shows you how to use models

27_Sandman_40 posted...

uJYgowW_d


this is just like the first set of images you posted.

it's not like any of this means much to common core. it's literally just a set of standards.
take for instance the above image with the decimal models. look at the standard it's referencing: http://www.corestandards.org/Math/Content/5/NBT/A/3/b/
pasted text here: Compare two decimals to thousandths based on meanings of the digits in each place, using >, =, and < symbols to record the results of comparisons.
is that not a good thing for a fifth grader to be learning?
your issue isn't with common core but with specific teaching methods certain instructors are using, which are then further taken out of context
