So would it have been wrong to add 5+8 then after subtract 3?
But then your final answer is 10, which is indeed wrong.
The question was just phrased poorly to begin with. It's really asking the student to "show how to use 10 as a base for adding 8+5". And then the teacher did a really terrible job of explaining the answer.
Ultimately the point is to show the kid that to do 8+5, rather than adding both numbers together at once you can go 8+2=10+3=13

But isn't that just overcomplicating things? I mean, I've never had to deal with this new form of math, but isn't it easier to say "8+5=13" rather than "8+2=10+3=13"?
Welcome to the world of common core math. The first time my kids brought this stuff home I was like, welp, there goes the education system. But it makes sense once you get the whole base-10 concept.
Yeah, I can get that with bigger numbers. But with smaller ones, it's better to teach it the "normal" way so that it simply becomes second nature.
"What's 6+5?"
Student A: "11"
"What's 6+5"
Student B: "Well, first you have to add 4 to 6 to get 10, and since 5-4 is 1, you add 1 to 10 and get 11."
Meanwhile, Student A is already halfway done with the test...
JordanStaalBestStaal said:Yes. Kids that are fairly bright absolutely hate it(from my experience at least). It helps the kids that can't do math at all at the expense of the intelligent students.
This system forces students to do multiple, rapid calculations as opposed to memorizing static number relationships. It's hard to see how that would hurt the "intelligent" students and favor those who are bad at math.
I don't teach, but I tutor in math so I could just be judging from a non-normal sample. But quite a few of the kids I've helped have been very smart compared to others of their age, but they do very poorly in math class. The thing is, they are usually very good with math.
I'll start by giving them a list of math problems, some for below their age, at their age, and above their age. Most have no issue doing math a grade or two above their own. I'll tell the parents "Yeah, your kid is actually very good at math. I'm not sure why they aren't doing well in class."
Then they show me the graded worksheets or tests from school and it's a nightmare. If the students reach the correct answer without using the common core method, their answers are marked incorrect, despite their methodology being more time efficient. That is the main reason I dislike the system, it eliminates any creativity. I wouldn't be against it if they taught it but did not require it, but requiring students to do math in a specific way is going to harm as many as it helps.
If you ask the students why they don't do it the way their teachers want them to, they often respond with "I don't need to" or "It takes too long".
For those that can't do math well, it makes things easier to process. For those that can do math well, it is a waste of time. The poor grades despite getting correct answers leads to students becoming frustrated with school and quit trying.

Didn't an NHL player get busted for putting a Pornhub tweet out?
I'm sending my kid to private school, even if I have to work a second job.
"Show Your Work"
The most terrifying three words you can say to a math or physics student.
Overrated. Just live in a good school district.
