You know what really grinds my gears?

Re: You know what really grinds my gears?

I like the mindset, and even more so like the assessments that can come from it. I don't like the textbooks, standards, or overall in-class practice.

I don't know. Squares upon squares upon squares...it's more confusing than helpful to me?

this makes me want apple dumplings.

I hate plastic bags, can never get them open

One thing I've noticed about those bags ... I swear when you go to nicer chain grocery stores they are easier to open than the ones in those discount pack-it-yourself places. Whenever I go to my local nice grocery store I have about a 90% success rate, while at the cheaper place it's 50/50 whether I'm just going to just give up and throw it in my cart without a bag and give myself salmonella/covid.

Are you talking about this?




Or this?

I guess the bottom line is if you want to have an approach to do bigger multiplication, the other version is always there. Hell, the calculator is always there.

What they're promoting on the left side is something involving number sense. Will you literally be drawing those things as you progress through it? Heck no. It's sharpening the axe before chopping down the tree. That's going to fire neural synapses, and that's going to get kids to be able to do that math mentally and on the spot. It's the way my brain always worked as well (as we weren't ever taught that way).

What infuriates me more than anything else is when a student gets something obviously wrong and has no sort of recourse or recognition in the incorrectness by the problem's nature alone. If they do 59*23 and somehow get 847 without thinking twice about: "Wait a minute, it should be more than 1,000 because 50*20 is that much," that is a bout of red flags everywhere.

For every student that doesn't want shortcuts to things, remind them about y = mx + b and the quadratic formula, and see if they can be more open-minded after that. That's all.

looking at those figures, all I can think of is ways to build blocks so I can set up the straight 4 block tetris piece to the right

The most important point to understand is that this instructional approach isn't designed for you, it's designed for the conceptual development of emerging math students. Common Core's approach is conceptual with the heavy use of supportive models and alternate algorithms which is part of the steady design to reach the learning of the common algorithms. The Common Core approach gets a terrible rap because of the lack of understanding of its intent.

I acknowledge, understand, and furthermore reinforce this. I have yet to master this, but in a perfect world this is how it would look. In some respects, I just don't like it as much. I'm not saying it's not better/worse, I just didn't come into the job hoping math would dominate in this setting is all. It's absolutely enriching for the students though, no doubt.

The book I'm working out of right now is so bad, though. I mean like... it has errors galore. Not only that, I feel the topics are presented way out of order, and they don't do the kiddos any favors when it comes to their examples versus their problem set, or their pre-made axes (going by 2's and them giving them a fraction y-intercept), things like that. But the errors really, really kill me. We chastise the book and its errors on Zoom all the time, haha.

I also think an additional problem is the fact parents simply don't understand the premise and because its different from what they were taught its "bad." Which rereading this is just piggy-backing on your post lol, but I see parents bitching about this a lot.

I think it's easy to summarize the common core discussion into our education system as a whole as a gear grinder

I get the "blocks" method but what's wrong with memorizing multiplication tables? What about using the "carry over" method when adding/subtracting.

It takes me 5 seconds to do 310-220. It takes my 10-year old niece like 2 minutes to write out all these blocks to do the same problem.

The old way is simpler to me.

When you do 310 - 220 in your head in 5 seconds how do you do it?

If in your head, your imagining carrying over numbers and whatnot I don't think you're being honest with how quick it takes. (If that's just an easy equation, think of doing a more complicated multiplication or division equation)

In that equation, I would do (320 - 220) + 10 in my head to get to the answer in about 5 seconds. If I was trying to figure it out by carrying numbers, I would have to get a pen and paper.

I have a lot of problems with the way block math has been introduced and is being instructed but I don't actually have a problem with it in theory.

It teaches kids how to critically think through a math problem without a calculator which is something almost everyone has quick access to these days.


I have a big problem though when I see kids scored as being wrong for coming to the right answer but not being able to provide the "correct" proof. That's the part of core math I have a problem with.


EDIT: And just to be clear, I know you are good with numbers and probably can figure that problem out with just looking at it BUT the point of common core math is to help those easily solve math without a pen and paper on the spot.

Re: You know what really grinds my gears?

I agree fully with you.

The video I shared does make sense when broken down that way. The issue is that how its taught in practice is just blocks and blocks and blocks where homework looks like a lego set when done...and it's required by the teacher.

Yea, agree with that 100%
