Alright you need to explain this to me
>>76155780
This.
OP is a fag.
>>76155711
I do not understand, what is wrong here?
>>76155711
think of it like working out
doing 5x10 bench isn't the same as 10x5 bench
>>76155711
can someone give redpill me on common core? i hear people complain about it all the time
>>76156143
Literally what
>>76156239
>think of math like a nigger
>>76155711
But 5+5+5 does = 15
So does 5x3, 3x5
>>76156143
I donut even understand this, the answer is correct but whoever marked it is retarded, literally the table is in a different order
>>76156239
Yes it is. If you dont change the weight it is the exact same workout.

Are we doing this then? OK, here we go.
>>76156447
no, it's not.
doing 10 reps of 250lbs will always be more difficult than doing 5 reps of 250lbs, even if the total reps for the session are the same.

This 'counting up subtraction' triggers me the most.
>>76156540
Its still the same numbers in the end family, 3x3 = 9, 3+3+3 = 9, 3squared = 9
>>76155711
just because that number looks like a 5 doesn't mean it identifies as a 5 you bigot cishet literal shitlord
>>76155711
They're teaching the process not just throwing a problem at them and telling them to find the answer however they want.
That same process they're teaching is extremely useful in higher level math because it helped to compartmentalize complex math into smaller steps.
>cue the wave of math illiterates telling me how dumb common core is because they don't understand what is literally grade school math
>>76156787
The coincidence.
>>76155711
>>76155711
>>76156143
They are ignoring the fundamental property of the addition and multiplication, that they are COMMUTATIVE, in order to reduce confusion with division and subtraction which are not. Whether this causes long term confusion nobody really knows yet, but it likely wont. No reason they should mark kids wrong on tests for it. 5x3=5+5+5=15 is mathematically factual.

I must admit that's how I do things in my head. Take them up to the nearest 10, 100. I think it's more from when I worked in retail before it was all computerised and it was the easiest/quickest way to give back change.
Something's $26.30 and they give you a $50 note
another 70c makes 27
another 3 makes 30
another 20 makes 50
So you give them $23.70 change.
But common core is still beyond retarded.
>>76156540
I wouldn't defend this, but still, if the teacher want's you to write it out the long way, then your spending more time thinking about the problem your doing. If anything, it's drilling in the concept harder then the other way around, so it's a good thing.

That would be reasonable, but under common core, there's some kind of weird "doubles plus one" rule for the ones digit and they break non-10 figures into basically random factors for no reason

common core isnt about getting the correct answers, rather your graded on HOW you reached that answer and according to common core there is only 1 right way to do anything.
>>76157149
This is also accurate history, right?
>>76156556
Wow did you pass algebra or are you a nigger?
A 10x5 at 100 lbs is 5000 lbs
A 5x10 at 100 lbs is 5000 lbs
Provided both are done in the same amount of time with the same range of motion the amount of work done is literally identical
>>76157064
They will not, stop with your retarded bro-science. If you are doing the same amount of weight with an appropriate amount of rest between sets you will see absolutely no difference.
All doing more reps does is burn out your energy systems, you will see no difference in hypertrophy.
If you want more muscle, increase weight AND time under tension.
>>76156827
it is breeds incredibly bad habits for these kids though
imagine you are moving on into high school and you still need to say out loud and spell words before you can write them down
the multiplication table should be competently memorized and committed to memory so you can instantly snatch the information you need just like both basic and intermediate vocabulary

Both are equally correct for number one. Infact I would argue the kid has a good grasp on the concept of multiplication if he was able to explain the answer in his own (not taught) way.
Number 2 is incorrect. Matrices are written as ROW x COLUMN.

if the illuminati or something like it exists, the leader's severely compulsive son made him implement common core mathematics. it's absolutely nonsensical.
you can teach a grade school student calculus with the proper curriculum, but instead these idiots are over-complicating basic mathematics with nonsensical bullshit. I think humanity will need centuries to have proper public schools.
>>76156914
If you were a personal trainer then you'd know that doing 10 reps 5 times is harder than doing 5 reps 10 times cause there are more breaks in between
No we dont
Theres a reason why pyblic support and respect for academia and educators is at an all time low now. I dont think ive met anyone with a kid who is actually happy about common core.

>>76157178
>obama brought the country together everyone
>>76157285
NASA makes reasonable guesses like this all the time.
>>76156732
Here's the thing about common core, a lot of the stuff like this example are really damn useful tricks to know. Most of us who work with numbers decently often figure these little tricks out on our own, but would never use them on numbers like this because they're simple as fuck problems. These are laughable just because they're doing them on simpler problems than they're useful for.
Part of the problem though is many of these tricks are idiosyncratic. Some are useful to some people, others not so much, and the intuitive nature of them makes them hard to teach.
>>76157319
You know I always found 14 - 8 difficult. Glad they simplified it.

Literally the opposite.

>That same process they're teaching is extremely useful in higher level math because it helped to compartmentalize complex math into smaller steps.
>the multiplication table should be competently memorized and committed to memory so you can instantly snatch the information you need just like both basic and intermediate vocabulary
What makes you think they aren't learning their multiplication tables?
They're just teaching the concept of multiplication itself using compartmentalization. Once they've got that down they memorize their tables.
>>76157198

>You guys should literally be able to do this.
>>76156708
There's a difference. In pure number of reps there is no difference. The difference comes in a new variable: time.

Seen this faggot before. He stumps himself unfortunately.
He constantly reminds the viewer that HE is "terrible at" and "hates" math. Yet he learned it on the old system which he is trying to somehow argue is better???????
There is a distinction between common core as a political ideology and the "new math" shit that gets shitposted.
Honestly the only reason this new math is creating such a mess is because the teachers are underqualified and don't understand the material well enough themselves to teach it. Sad!

Yeah this is fucked and really goes to show how schools pander to the retards. Rather than focus on what any bright child would realize (That either process will result in the same answer), the school marks a student wrong for developing their own problem solving strategy rather than follow a certain predetermined, and possibly unintuitive algorithm. Fuck common core.

Read it. One person eliminates the days and another eliminates the months. Once one of them realizes that the other does not know, it solves the puzzle because it leaves only the correct answer.

>>76155711
Handwriting expert here (its a side thing). I can tell that the numbers and letters were written by the same person. Look at the G and the 5's. The hook on the G has the same curve as the top of the 5's. Further looking at the o the R and the 5's we see the same basic structure.The slant on the third 5 in 5+5+5 is the same as the R and the third and second five of the same series have the same "twist" on the bottom as the o. Further more the structure of the 3 and the W is exremely similar. If we turn the W 90 degrees counter clockwise it is exceedingly similar, the difference comes in that when writing a W he is basically writing a 3 from the bottom up as compared to the top down.
Also why is your whiteboard so fucking dirty?

>compartmentalization for such a simple process is BAD, there is literally no questioning this
Lolno.
It's a concept that needs to be implemented early and often to be used effectively.
I've used this method my whole life just because that's how I've always preferred it (yes, even for multiplication). As I grew up I learned how to do more and more math without thinking. The math I still need to think about I use this method and I'm much faster than most folks at my level.
Also it is easier for multiplication in general.
People like you just glace at the process and screech
>LOOK AT ALL THOSE STEPS AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
but it's 5, 1 second steps instead of one 10 second step. Once you learn it naturally it's extremely easy and fast.

I still find it confusing and misleading because of the weird language.

whtecapes common notice is te common core MANDATED grading system. it flattens distributions. imagine now grading is out f ten points but common core changes it to a three point basis. before there was a HYGE gap between whites who score seven to ten and blacks who score two to five. Now the blacks who scored five are grouped in the same group as the hites with seven as two on a three point scale.
ALL of the problems are multiple choice OR GIVE YOU THE ANSWER.

Arrays take about 1 minute to understand and if your higher math people have no issues understand it I don't see why it'd have to be moved down.

What the fuck are they doing here? I had to find the answer and then look at the 'solution', only to realize they did some fuckery that's now shown or explained in any way.
I assume they're teaching kids to get to multiples of 10, then use the remainder to do the addition. However, this is just fucking retarded.
It's like they're teaching shortcuts that are only applicable for the portion of the curriculum they're on at that moment. Are they going to continue with this garbage when they get to more complex problems?
I just fucking memorized basic addition, subtraction, multiplication, and division. We had tests to drill that shit home until it was completely memorized.
It's way better to make math second nature to a kid than to have them logicking their way through these rudimentary problems.

The answer they are looking for is D as you are supposed to change 8 into 10 and 6 into 4 so you get the answer of 14. It's all about moving around the numbers into easier to manage ones and then solving the problem like that.
No you can't just add 8 to 6 you fucking racists.
>>76158192

>not getting it even after I give the answer
She either is giving 4 bags or 6 bags. (maybe 2 of her friends aren't sure if they can make the party)
If her 2 other friends can't make the party, she will give 4 bags. And then any multiple of 4 stickers (4 stickers => 1 sticker in each bag, 40 stickers => 10 stickers in each bag) would work.
If the other 2 friends DO come, then she will need to buy stickers in multiples of 6 to avoid leftovers.
Since she doesn't know for sure if she will need multiples of 4 or 6, she can actually buy in numbers that are multiples of BOTH 4 AND 6, which happens to be numbers 0, 12, 24, 36, etc, ie multiples of 12.

>Arrays take about 1 minute to understand and if your higher math people have no issues understand it I don't see why it'd have to be moved down.
Teaching something earlier allows for more to be built on top of what's already learned.
Imagine if you didn't learn addition until grade 12. You wouldn't be able to learn algebra, trigonometry, calculus etc etc
>I don't see why kids would need to look at multiplication in an array way
Arrays are used a lot in higher level math classes. The first time I ever saw an array in my life was in 10 or 11th grade and I know I would have appreciated previous experience.

>Bernard has deduced that Albert has either August or July. If he knows the full date, he must have been told 15, 16 or 17,
how has bernard deduced this without asking albert what month he was given? and how do we know what albert told bernard?
also, if albert and bernard are cooperating, they would simply KNOW the date fully, there would be no guessing

Kids don't fucking understand this shit. They count on their fingers and use bits of eraser to figure out math problems until they figure out how to just write it out.
This kid's being told to "Explain how he got the answer" to 17+25. This must be ruthlessly confusing to him, because to him, all he did was add. I'm sure he was instructed NOT TO SAY that all he did was add, so he had to come up with some other fucking way he came to that conclusion.
Because to normal, rational human beings, even children, simple math is simple math.

Mathfag here. The goal of this is to teach conceptual understanding not just be able to compute what a calculator can do. There are math structures which are not commutative i.e. a+b !=b+a. In this case of these structures it would be the case that if you had x*y it would mean you add y a total of x times. Common core gets shit on a lot, and for the most part I agree with that its shit, my main qualm is that it assumes a one size fits all standard for all students, but the main goal in teaching concepts rather than algorithms comes from the right place.

>It's better to teach things in familiar terms. If they just learned multiplication it's probably easier to visualize then applying that same thought process to Bob's cuck shed.
Kids are very impressionable though and you need to drill something through to them before they can move on. As long as you teach multiplication the non retarded way first I don't care how you further screw up their education.

That's fine
For more complex math
This is 2+2
But you have to do 2-1 then take that 1 and add it to the other 2 than do 2/1 to get the other 1 and add it to 4 because 2x2 is 4 then subtract 2 from it and then you give your closest estimation to the answer. 6 is an acceptable answer because it is close enough.

When it is too easy for the grade it's currently being taught at. You know, this isn't anything new. Multiplication was the pinnacle of high school education back in the day. Standards get higher and higher and students get smarter and smarter. That's the goal.

You know matrices aren't part of common core right? They're something already used to help teach multiplication. They're part of your "non-retarded way"
Common core is a completely different process that deals with compartmentalizing the problems into smaller, easier problems.

I don't care if you try to bring down topics. All I think is that they should be sufficiently separate from one another with appropriate links. The average small child doesn't have a great capacity for abstract thought so simple things done over and over work better than you trying to prepare them for matricies.

Do you remember being a kid
Maybe you weren't a smart kid
Smart kids get bored in school. They discover the solutions to problems very quickly and then become bored. Bored kids become "problem kids". They get detention. They get expelled.
Now imagine you've got little Timmy who knows off the top of his head what 5x3 is, and he knows why, he knows it's because it's 5+5+5 or 3+3+3+3+3. He knows it's 5 3's or 3 5's. To Timmy this is sufficient information.
Timmy has solved the problem the moment it is presented to him. Unfortunately, now the teacher has to delve into a philosophy lesson as to why 5x3 is the way it is. Timmy is bored, and well on his way to being a problematic troublemaker that gets detention because the teacher spent 20 minutes explaining a 20 second problem.
School is about more than programming children. It used to be, at least.
>>76156606
That is a good "advanced technique"
When you are dealing with quick 2 or 3 digits calculations, It Actually works pretty well.
But that is late high school grade, when the numbers simple add up without problems. Teaching a kid how to do it is retarded. You are supposed to start with the basic and aprimorate It till you reach the complex.
Otherwise, we should skip any form of first and second degree equations and start teaching 5th graders calculus. After all, they gonna learn It in the future, Why not start by the proper way? :^)

I think you're misunderstanding something...
They're not teaching matrix multiplication right after they teach normal multiplication.
They're just using them as an aide to help teach multiplication while also introducing a concept that will show up later (matrices)
It's just a visual aide like any other drawn diagram except years down the line a kid will be able to say "hey I've seen that before"
This is how teaching works. Everything is taught as an introduction to the next step.

If the retards Still talknig about 5x10 or 10x5 when working out:
The ammount of "work" (force X displacement) is the same, but It might not be that obvious, but the point of working out isnt just do some "work" value. Working out is slightly damaging the muscle, so the body rebuilds It, a little stronger.
And thr damage done by being under some repetitive force IS NOT LINEAR. It is actually very exponential.
You might damage a machine with 5000 cicles at 50% power, or damage It with only 5 at 100% power. Damage due repetitive force isnt linear.

>>76158091
>Why is this weird/wrong?
that you could do this in your head and still keep up with the normal lesson would mean you're pretty normal. some kids might need this because they just can't grasp what is happening conceptually. Like when I was in 1st grade there was a kid who had to use an abacus to do simple adding and subtracting. He just had difficulty grasping the concept in his mind of 'five..take away three and there are two left'. the abacus helped him. this is kind of like and abacus for everyone, and that's the problem. Not everyone needs an abacus, it's slows the normal kids down by adding more steps to what should be a simple problem.

Yes, it's all part of this: https://en.wikipedia.org/wiki/Anti-bias_curriculum
>The anti-bias curriculum is an activist approach to educational curricula which attempts to challenge prejudices such as racism, sexism, ableism, ageism, homophobia, and other forms of kyriarchy; the approach is favoured by civil rights organisations such as the Anti-Defamation League.

It's so simple that adults look at it, scoff and shit out the answer because of course they know it. Many kids can probably do the same.
But that's exactly why they're using this easy shit as an opportunity to teach a better PROCESS so that when they get to stuff where they can't just shit out the right answer they will have a better way to find it.
People like you are used to how they were taught in school that there's one way to add, one way to multiply and one way to do everything else.
but there's not.
There are some thought processes that are quicker or more efficient or more accurate etc. When people are better at math than others is it always 100% because of how they think not some innate connection with the gods of math or some shit.
Instilling this thought process in everyone will drastically improve our math literacy as a whole.

the problem people have is that there is basically no way for bernard and albert to converse/deduce a solution without saying what they were given for information
the reader gets strange insider information on a collaborative event that literally cannot happen and still leave doubt to the answer, yet somehow albert and bernard "know" things about each other regardless
the problem also makes a grave mistake by saying bernard was given the date of her birthday, so there is literally no conceivable way albert would know bernard had the *wrong* date and therefore did not know the day of her birthday

Yes, if you actually put 100% force on the bars, but for some weird reasons, we cant do it. otherwise you wouldnt even need bars, just moving your arms at full force would do it.

i'll be honest -- i dont know how much time kids get in the us. where I live, elementary is typically done in long periods but you don't spend very long on any single activity. like if you have French for an hour and a half, it won't all be on reading and analyzing the same story, you'll do some quick grammar, then read a bit, then maybe watch a short video, then give some oral presentations, then maybe do something totally unrelated to french, but just in french the whole time. keeping things relevant and organic is the key to keeping students interested, not just throwing them in the woods for 15 minutes every hour

>>76156143
These are arbitrary rules they are making up. Why are they teaching arbitrary rules? For example, the problem is stated to use repeated addition to solve for 5 x 3. They would have to have some kind of rule to determine whether your write 3 fives or 5 threes. So they are creating this whole arbitrary system to help with basic addition and multiplication?
>>76160482
In the US some schools limit kids to 30 minutes of recess per day, and that's time they have to share with eating lunch. So if a kid spends 20 minutes eating their lunch and socializing, they have 10 minutes to exercise and play.

For them to use it in their head they have to know they're doing it right. Seeing as teachers don't usually have telepathy I'd say they have to write it down to make sure.
It's the say was as we always had to write down that "carry the 1" shit when we did addition. We all fucking knew to carry the one but the teacher had to have something to check us by.

>>76160702
It is like a programming language, they are going to teach these protocols for how to do basic mathematics. An array is always row by column according to my arbitrary rule set. That's bullshit. If you have a problem such as that you shall specify what you are expecting of the student. Making them memorize any arbitrary rules is a waste of time and brain power.

Name a function that would be confused by the old math's lack of compartmentalizations outside of calculus. And within calc it's straight forward that you should pay attention. Common core is explaining one relationship while ignoring another. Kids don't even get that addition and subtraction follow the same rules now.

>>76161455
Yes that is exactly what they are doing, giving a lesson and making them memorize made up rules that no one else uses, which have no real life application. Who is going to make use of the knowledge that in Common Core math an array is written as Row v Column. At least if you are going to memorize some kind of rule set, for gods sake just learn programming. That is actually useful. Stop being dense.
>>76161230
>They (you) are using language, not mathematical procedure, as a means to confuse, alienate, and control minds that need to be enthused about the subject
Keep showing your ignorance.
Math is arbitrary. Everything flows from your base assumptions. Change base assumptions, and you change everything afterwards.
In the same vein, notation is customary and not fully formalized. Symbols and conventions are *ALWAYS* explained in a work as to precisely how they're being used in that work because even mathematical notation is not fully explicit on its own.
You have, at best, a mechanical understanding of mathematical operations, nothing remotely resembling an actual understanding and are therefore entirely unqualified to speak on this topic.
>>76161497
My best friend at senior high school, who was top in maths and sciences and now owns a GP practise, couldn't add for the life of him. Well he could, but he was too lazy, and in most of the applied maths, calculus and physics he was doing, it was barely necessary (actually I was as good as anyone in the school as far as arithmetic went)
>>76161601
No, you explain using common core ;)
>>76160530
i have no idea where you went to school but that was not my experiance at all (texas).
we got 30 minutes for lunch and between an hour and a half to half an hour of recess depending upon our grade, higher your grade, the less time you got. recess ended all together after 5th grade though. thats when we got longer "electives" like band or art or some specialized computer or buisness class instead.
our lunch time included waiting in line though, which took forever, so now I've been trained to eat faster than Michael J Fox at Bootcamp.
>>76161301
There is no such this as division or subtraction in the field of rationals, they are abbreviations for operations with inverses.
Lets work with a different ring, so you can maybe understand. Suppose we had the ring of square matrices, and you wanted to exponentiate them. Let A be a square matrix and n an integer, then A^n, would be the matrix A multiplied by itself n times, not n multiplied by matrix A, that makes no sense, order matters. The same idea works for the integers. Suppose you wanted to repeat the operation of addition n times on integer z. Then you would write it z+z+...+z n times as n*z, not z*n. Yes both work but that is only because integers are a commutative ring.
>>76161442
If you read it in english, it's actually you multiply 5, 3 times.
>>76161582
It's not that the way we were taught math is more confusing it's just that it's slower and less intuitive (yes, I know you don't believe that)
Getting this thought process into your head at an early age just makes you generally better at math because all complex calculations can be broken down into smaller steps.
This is extremely true of calculus where you can take up entire pages with calculations.
