bullshit like this is why i dropped out of high school junior year and just went to college it doesnt matter if you can do the loving math in your head you have to ~show your work~ and it drat well better be the specific version of the work that is endorsed by that teacher

this poo poo is bait. just don’t penalize students for coming across a correct solution, whatever it is. teachers missing the forest for the trees poisons a lot of minds off math and makes people think they’re bad at it, but that’s a fake idea, it’s a failure of pedagogy

That's because the average teacher is an overpaid loving moron. Most teachers I've met have the skills of a Walmart grocery bagger but whine and moan they're not making a six figure income. Pointing out they don't work any holiday, half of December and the entire summer typically doesn't go over well.

long form is literally like three steps.

step 1: multiple the first number on the bottom row with the top numbers.
step 2: add a 0 at the start for every number coming next and do as before
step 3: add them together

It's not the steps, the main problem with the standard algorithm is that the carrying is a lot to visually keep track of...you're putting your tens place carrying right on top of the ones place carrying. Box method (aka lattice method) makes the carrying easier to see where it's supposed to go.

The common core math standards (as with the previous NCTM standards that they were based on) actually let teachers incorporate a lot of different methods and introduce a lot more rigor in the mathematical tasks we ask students to do. People have an extremely negative view of it probably because along with the implementation of common core came a shitload of extra testing, most of which was used as justification to close schools.

Yeah that's cause your teacher's a dick, not cause of common core. Unless the directions expressively stated you were supposed to use a visual model or something.

im actually curious about these teachers that have to buy their own supplies. like when i was a kid we were expected to bring all our own supplies because the school didnt give us poo poo and all they did was stand up at the front of the classroom all day teaching from a book/ppt/handing out work sheets

I feel like I've seen some weird poo poo where they were like
what's 5 x 8?
well, think of it this way,: 5 8's is a lot like 5 10's, which is 50, and 10 minus 8 is 2, and 2 times 5 is 10, and 50 minus 10 is 40
so 40!

and some facebook dad was like WHAT. WHAT THE gently caress? WHAT.

Or for your same 5 x 8 problem:
10 x 8 = 80, so 5 x 8 = 40.

I run into this all the time figuring out tip when out to eat with my friends. They always hand me the check to figure it out.

Bill is $75.60? So 10% is $7.56, therefore 20% is $15.12. Pretty drat simple. Math is one of those things that is not stressed as much as it was when I was in school, and now we have kids who can't make change for a buck. Hence, less STEM students.

I'm pretty sure there was an episode of the cosby show where one of the kids was doing math in base 12, and bill cosby was like humpty-dooooo this is all a bit much for me

New Math was a curriculum which is the day to day how to teach it kind of thing, and Common Core is an attempt at creating a federal standard of when kids should know what. It doesn't mean you're getting good textbooks from the University of Chicago, kids in the south are still getting weird Texas textbooks so all the same your results may vary.

Cubone posted:

Should be done by grade 3, according to common core. Though in my experience they kids are done with it before Christmas, most of them probably before Halloween. I mean don't forget you gotta know your times tables before you can even do the long form method.

The Great Twist

i learned the normal way with carrying the one and poo poo. also memorizing multiplication tables up to 12x12.

it only took me, i don't know, a year or so, to do that "box method" in my head without being taught it. also i learned to just reduce everything to 10s and add the rest or double as needed

basic math isn't hard and if you have a problem with it you might be a retard. good way to weed out the future trumps in society if you ask me

that's true, but don't they use the same lesson plan every year? seems like a lot of that stuff is work that gets sorted out in the first year or two. i mean all that for 50-60k isnt unreasonable. i imagine there's low level office jobs that expect a similar amount of work for less
