***EDIT*** you want to know what REALLY grinds my Gears? Hehe
Here in the states, I get super pissy when elementary teachers complain about Common Core math. As a secondary maths teacher, I understand how almost all the CC math vertically aligns. There are first graders solving one step equations. This kind of math is happening in little minds right now... they are building and recognizing patterns EARLY. They are getting a HUGE curve and on the same playing field as other European students. American elementary teachers say crap like,”Math is HARD” and “I don’t want to do math kids, but we HAVE to”. This ruins the experience for them and MAKES them afraid because an ADULT won’t take 20 minutes a week to teach the BASIC material to themselves before muddling through for the children. I spit on the ground you walk on for purposely shaming a beautiful subject, and making it more difficult for both students and future maths teachers. Thank you for coming to my TEDTalk
@SchroedingerPussPuss, common core blows
@SchroedingerPussPuss, people don’t like common core because people have been accustomed to memorization over learning. And even so learning does not teach understanding. Common core is a step in the right direction and can hopefully help people understand math.
@ericthegreat, reminds me of your father.
@Implicit88, seems as though your calculations are incorrect.
@SchroedingerPussPuss, I wasn’t listening could you repeat that?
@SchroedingerPussPuss, I have seen empirical wrong things on the internet from common core. Such as a student being marked wrong for saying representing 3×5 as 3+3+3+3+3 instead of 5+5+5 based on how they defined multiplication. This is outright wrong, saying 3×5 and 5×3 makes trigonometric identities and factoring impossible. This student was marked down for making an intellectual leap.
@codyl, that’s because the teacher doesn’t know what the hell they are doing. I dislike that elementary teachers are only required to get through College Algebra in the states. They need at least an additional 9 hours to fully help our students.
More like if 7+3=10 and 6-3=3 and 10+3=13 than 7+6=13
@Peppermint Butler, much more accurate
@Peppermint Butler, Sadly I do both
@Peppermint Butler, then, Jesus Christ
Sorry for the long essay...
Okay so I'm actually a Math teacher that finished out a bunch of university math courses last year and this is a conversation that I started having with everyone I could! There are some many different ways that people process the mental math and it's really cool to hear how people's brains work. I also found for some of my friends from High School they didn't have some of the shortcuts (like taking an easier 7×2=14 & 14-1=13 then 7+6=13) and because of that they didn't know how other people were dealing with it faster than them and they start thinking that they just can't do math. Everyone can do math! There are a bunch of shortcuts and processing things that are so interesting and make it easier for everyone that we just do not teach at school! Anyways this has been your nerdy Math Teacher rant of the day. Hope everyone is doing well :D
@SomethingAboutMemes, Math is cool like that. For me, it would be 7+6=?, 7+3=10, 6-3=3, 10+3=13. That's how I've always done mental math, and as things got more complicated in school I would always get marked down for not showing my work because I would use the paper to "hold" my numbers while I was working on them. I'm pretty darn good at math, but showing every step would mess me up. I don't know why. I only had teacher in my academic career who let me talk them through my process and stopped marking down my work and tests.
@SomethingAboutMemes, I like literally just walking my second grader through this in the car.
7*12 is just 7*10 + 7*2
I think 6+6=12 +1
I hated math as a kid, hated it in high school, hated it in college, so I got a career that doesn't have anything to do with math but now my sons are doing 4th grade common core math at the table and they need my help so now I need to learn that too. There is no escape.
I do this alot with alot of equations.
That is actually a strategy called doubles minus one that is still taught today.
