That being said, the worksheet is stupid. The things I just described don't really fit that problem. Don't blame common core and alternative problem solving strategies whenever you see a shitty worksheet.
And keep in mind most adults (including teachers) suck at basic math. So they have no idea what they're talking about...
...but that doesn't mean Common Core is bad. Just idiots implementing it.
The idea in OP's pic was twofold Firstly, it supposedly helps students "make sense" of numbers by illustrating how numbers can be broken up and rearranged to get the same sum Secondly, its supposed to simplify adding my making 10, which is an easy number to work with In practice however, this system is retarded as fuck. It moderately helps the high level kids but completely fucks over mid and low level kids.
Good news however is that this system failed so spectacularly that its being phased out now and will be gone completely in another two years or so

>>702916426 I think the complaint was about how arkward and needlessly complicated the question was worded. It should just have read 'Break up the numbers in a way that makes addition easier' or whatever.
No, not all people do this in their head - that's the problem. Educators noticed that a large number of students were not understanding how math works, they were just memorizing well enough to pass and move on. They didn't just complicate math for the hell of it, they did it to make sure all students were forced to learn math rather than memorize.
>>702918330 That's my fucking point. It absolutely doesn't have to be. Word the question differently and it's as intuitive as fucking walking. 'number bounds', 'skip count'. What do these words accomplish? Just show someone how to add towards tens and how it makes the subsequent addition easier.
>>702915967 That's actually how I do math tho. Always habe, they didn't teach it I just figured it out. Like say I the equation was 7+5, it was always fast for me to add the three then the two together to get twelve then just memorize the answer. But my brain works different because I had the umbilical cord wrapped around my neck three times. I'm not retarded or anything, just certain things I have to do differently. The way I add is different, but for some reason I subtract like everyone else. And I learned a different way to tie things, like my shoes. I am kind of depressed to know tho that common core is the way I do math, because for most people it's just more complicated it's not easier
>>702919048 Do you not get what I'm saying? Like at all? Instead of making it more intuitive for children, this stuff is actually obscuring a natural and logical way towards the problem. Math may not be intuitive for everyone, but shit like this is making it even more unintuitive than it needs to be.
>>702916426 For me it's more like I just solve the right column first and put down my answer and then the left column next and put down my answer. Sort of like how I was taught in school before math was declared racist and common core was invented.
26 6+3=9 +13 ____ 9
26 2+1=3 + 13 _____ 39
So the answer is 39. And I didn't need to take the extra steps to actually notate the mental processes involved in how you do it in your head on paper. Niggers.
>>702919424 After reading this thread I feel better about this, apparently this is common for people to do, and I've told people I work with about it but they act like I'm strange and say it's to complicated. It comes in handy for me tho, having a 0 to work with just makes it faster for doing in my head and it is easier to keep track of shit
But the answer in green is the correct answer because the question was a trick question to make sure the kid understood fractions. There is nothing mentioned about Marty and Luis having different sized pizzas.
How this annoys you or makes you REEEE is beyond me.
Marty and Luis go to a pizza shop. They don't like the same toppings so they decide to order two separate pizzas.
Each pizza comes with six slices.
Marty ate 4 slices of his pizza.
Luis ate 5 slices of his pizza.
How in the fuck can Marty have eaten more pizza than Luis? HE CAN'T, FUCK STICK! The question is a charade to make sure that kids understand fractions. What's sad is you guys think this kid saying "hurrr well I guess Marty got a bigger pizza because I can't into fractions durrr" is somehow profound.
Trust me, I hate common core. But this picture has no context and you're reading something into it, trolling, or you're just as bad at basic math as this kid who got question number 8 wrong.
>>702915967 >american education do you guys not have teachers? do you just go to school get homework and leave? this paper isn't supposed to teach you anything the teachers (are supposed to) show you how to do it in class first, and then give you homework so you can practice it at home or whatever >hey kids >this is how to do "number bonds" to "skip-count" notice the keywords >7 + 7 = blabla > / \ > 3 4
>"huh wtf is this question about" >"'number bonds', 'skip-count',.. isn't that what the teacher showed us" this is literally how the human brain works you associate things with other things you can put a shakespeare quote in the question if you want as long as the question can be recognized by the students there is no problem this system is perfect assuming my first statement is true
>>702920454 It states "Marty are more pizza than Luis" which is a known fact. It did not say how can Marty have eaten more pizza than Luis. Yes the fraction 5/6 is larger than 4/6 but that is not what they are asking
>>702920708 For the most part teachers are forced to teach this shit whether they like it or not. It wouldn't be their fault but rather the school administration who selected the material. > B.A. in early education
>>702915967 I've seen this before and was rather confused about it. But when I think about it, I do it, too.
When adding numbers I just subtract from one, and add to the other to make the nearest 10. So in this case you make 10 and are left with 4 so you end up with 14. Just makes for easy counting in your head.
>>702920795 the problem is parents and other people around them thinking common is stupid and making the children think so too in the end the kids won't even try because 'hurr durr it's bullshit anyway'
>>702921313 This is very true. My gf refuses to help our kids with they're homework because of it. I picked up on it pretty quick so it's not a problem for them but I'm sure their are a ton of kids who aren't as lucky..
>>702919990 It doesn't give necessary information at that point, then. It asks "How is this possible?" It doesn't ask "Is this possible?" Meaning that the 7 year old has better reading comprehension than the shitty teacher, and you, too.
I guess it's just asking "How to add and make 14?"
I used to just look at the shit in class and doit in my head quickly with some fucked about way that I couldn't explain to the teacher without being told I'm wrong, which was a problem because we had to show work or our answer was automatically wrong. Along with that, if the work we showed wasn't the way our teacher wanted, it was still wrong even if your answer was right.
>>702920625 The only thing this teaches is to look for keywords and then just automatically use whatever method you were taught. It doesn't make you evaluate the problem and understand the solution. The only thing that happens in your brain is 'I see this word X, so I do Y'. It's a perfect system to nourish mindless worker drones.
>>702915967 >they're teaching children math in a way that I don't understand and am unfamiliar with >I can't help my children with their math homework because I don't understand it >I could possibly learn these new methods with a five minute Google search, but I'm too fucking lazy and stubborn >It's much easier to complain about how stupid Common Core is, so I'll do that instead
>>702916499 Well you don't know that much if you don't know it was adopted by some states and not all and that phasing it out of one state means fuck all.
Side note, it was developed by teachers. It's actually a good system if bother learning the methods and terms. Of course, shit kids that get no help from parents will continue to be shit kids, so that point is moot.
tl;dr you're an idiot and have no idea what you're talking about.
>>702915967 God damn are you retarded or something? The question is asking what is 7+7=? It is proposing that one way to solve this is by finding the "number bonds" AKA 3+4 (which equals 7 for you retards) Then use these number bonds to easily add 7+7 by adding 7+3 to get 10, then adding 10+4=14 which gives you the answer to 7+7=14 God damn how can you guys be so dense?
ITT trolls don't understand Common Core math while small children do. They might be attempting to phase out Common Core wherever the anon who said they were lives, but at STEM schools around Chicago they seem to be keeping it.
Common Core math emulates the number structures of other cultures- namely Asian ones- who count like so: 1-2-3-4-5-6-7-8-9-10-10+1-10+2-10+3... Most European counting systems go: 1-2-3-4-5-6-7-8-9-10-11-12-13-14...
The European counting system makes rapid number processing more difficult, because it doesn't inherently clump numbers into tens, which is useful since we use a base-10 mathematical system. It's the reason Asians are better than us at math, or so they say.
References- I am an undergraduate education major who just finished 80 hours of observation in a STEM 4th grade class in the Chicago burbs.
I've talked to actual teachers and students studying education at the main university in my town and they all have said that the common core is a nightmare that they have to use because kids are losing interest in education. This is a struggle they are scrambling to fix.
>>702922515 I just barely passed until HS because there was actually a good math teacher. He asked me why I wasn't showing any work, and I told him. He'd ask me every once in a while on a new subject how I got an answer, and after I explained it he was okay with it. He was chill as fuck and the only reason I passed most of HS honestly.
Sidenote, I went to school in Texas, which doesn't have this common core garbage. It probably wouldn't be confusing if I was taught it or learned it myself, but I already know how to do math. No need in re-learning it in a completely roundabout way without a teacher.
>>702922741 I don't understand common core but I understand math. If you're taught it from the ground up without knowing another way, then it's probably pretty okay. If you look at it without having been taught it, then it's a jumble of shit imo.
>>702923102 The problem is with how ridiculously convoluted the question is. Adding towards tens is a pretty intuitive concept for most people. But the question uses so much unnessary vocabulary and is just so awkwardly worded, it would confuse the average student more than teach him something.
>>702920127 This is the correct analysis. Since Marty ate less, fraction-wise, but the question asserts he ate more pizza, the only way that is possible is if the pizza was larger, so he literally ate more by area.
It implies he does indeed understand fractions. And lateral thinking that would do a Mensa member proud.
Now if this question was in a section where he was supposed to determine true or false, then he got the answer wrong. But that would be the teacher's fault if he didn't know that.
>>702923370 Sure, the wording doesn't make any sense because you have not been taught what they mean. But, seeing as the children who have been learning this have probably been taught what these words mean. This should be a nonissue. I mean, I was able to just self-intuit what they meant by reading the question and I don't know the first thing about Common Core. Number bonds: a group of numbers that add up to another number. 3+4 in this case skip-count: Using the number bonds to count larger amounts than 1. So instead of saying what's 7+7? then counting from 7 to 14 one by one you skip some numbers. The wording outside of those is pretty horrendous though >"skip-count by seven by making ten or adding to the ones" Even knowing what skip-count means that sentence is fucking retarded. I can agree on that, but that isn't the fault of common core. That's just someone who is illiterate and can't form a basic sentence.
>>702922929 My teachers always thought I was cheating. They'd ask why I didn't show my work, I'd say I did it in my head, they'd make me do it in front of them. Ironically all the other students were cheating off of me haha
>>702915967 Day tell'n yo to skip count all up in da place nigga! Wat the fuck is wrong wit yo? It easy Seben plus seben be forteen, but yo can also be gett'n dare by by seben plus tree den four dat be forteen also. White boy.
So if I'm reading this correctly what one does in there head would be 7+7=? Then you split a 7 so now its 7+3+4=? And then just make a ten to make it easy? 10+4=14 I always did this shit in my head but is that what's being taught here?
>>702925897 Oh shut up, every human being should be able to do basic addition and substraction in their head, even with a calculator in your pocket. If you don't have at least a tiny smidge of intuition when it comes to mathematics, then a calculator won't help you one bit.
>>702924855 I actually slept through my senior year of math when since Mr. R taught Seniors, too. I would do enough work to know I knew how to do it and then copy of of the other people to get my work done. It would've taken me too much time since I was too late to check out a Calculator because my school only had a limited amount. One day this bitch who tried to cheat on my best friend with me decided to keep me from copying because "I'm too dumb and don't deserve to pass." Asked Mr. R for the weeks work and got it done in that hour, with like 6 sheets of paper filled with work. Can do anything without graphing calculators except the super complicated graphs.
Fun part is she tried to get him to fail me by saying I was looking up the answers, even with my pages of work. He laughed.
Freshman year I only did half of my final, but since I got everything I did right he gave me 100 anyway.
>>702927017 Yes, fucking well after elemantary school you still should not overuse calculators. I know exactly where it ends. Kids typing in 13+8 into their calculators because it's just their first instinct. They don't even look at the prbolem before taking out their calculator. You can't do advanced math without understanding how numbers work and what terms represent. A calculator takes that understanding away from you.
