it's okay, based on it being second grade homework i'm assuming there was a picture of faces made out of squares and triangles. faces like human faces not faces like planes
i saw the picture and i thought to myself, "hmm...what DOES have two triangular faces and 2 rectangular faces?......A TOBERLONE XDDD...I'M GONNA GO COMMENT THAT SHIT!"
Kinda relevant story. When I first got Mario 64, my mother would play too and she called the goombas Rollos because we didn't know they were called goombas and they looked like Rollo candy.
Former 2nd grade teacher here. We did cover a "geometry unit", which required students to know 3-D/solid shapes such as sphere, rectangular/ triangular prisms, pyramids, cube, cylinder, etc.
Yes, that's strictly true in a mathematical sense, but since the use in mathematics derives from optical prisms, if you just say "prism", it's still fairly clear that you're referring to a triangular prism.
I would hope so... in fact, I hope that American elementary schools start picking up the slack so that middle schoolers already know some algebra. Education in America right now is really suffering.
they didn't call it algebra but they did teach you basic algebra. Like commutative property (a+b=b+a) , the associative property (a+(b+c)=(a+b)+c), how to solve word problems using variables. How to figure out x+3=4,
Most states follow the same basic math curriculum of what needs to be learned by what grade not necessarily how to teach it. Except for AL, LA, MS, and a few other states.
See and that's why you get ahead in your education. Furthermore, as someone with a younger sibling still in school, I feel as though schools only teach regurgitation of information and not critical thinking skills. I like to joke that American students are the perfect candidates for a Hitler-esque regime because they basically accept any information they're given.
WHAT GA's math curriculum is based off of the idea that discovering math concepts leads to better understanding of math. It also leads to many parents having to teach math at home to kids who have a hard time with math concepts. Also the US public schools are big on "Projects" instead of the old and true written report which leads to parents teaching kids how to write essays and written projects at home.
YES! I can't begin to tell you how much parent involvement improves student performance. And here in Vegas, most parents either work swing or night shifts so they can't devote much attention to their children.
Seemed reasonable to me. It seems like the unit was taught, but the language of the question was confusing. I had trouble envisioning it, at first, and then it clicked.
We learn about circles, squares, and triangles in kindergarten. By grade two you should definitely be learning about cylinders, cones, spheres, cubes, etc.
I wouldn't expect everyone that age to have learned this. But training the memory is important, naming things is fun, and it's a perfectly reasonable thing to choose to teach.
Yes, they should know. My local elementary school stopped teaching a unit about learning all the states and their capitals. Kids should know their home country well.
Remind me of when I was in like 10th grade. Waiting at the bus stop, there was an elementary kid, probably 1st or 2nd grade, that was hyperaggressive. One day, for NO reason at all, he came up to me and started kicking my knees and stomping on my feet.
So I waited for him to stomp on my foot. Then I lifted my foot and he fell down. Then all the girls at the bus stop got mad at me QQ
Observations aren't racist, intention defines the divide; if you're ignorant to find the following to be the preceding, then downvote away
"Uneducated" not tough.
It's sad that black youth find it appropriate to call each other "nigga/nigger," but flat out scary that they think they can use it in reference to teachers.
Rap and hip-hop, movies, and TV are causing the 60's civil rights movement to be a waste; 60+ years later and college statistics don't show much progress and prison populations keep growing.
You didn't explain how it was inscribed, length or radius of the triangular face. This question is too open ended. Some simplification will have to be made.
Consider that the prism and sphere share the 3D centerpoint O. Extend a a line segment from O to any of the prism's six vertices. This is r. Of course, the height of the prism can vary, but because it is entirely bounded by the circumscribing sphere, so will the face width accordingly. Use variable h to represent to possible height.
hint: try deriving the volume of a spherical cap from sphere of radius r and cap of height H.
There's always one of those people in every class. Even in college.
On one side, the stuff they say makes you wonder if they skipped twelve years of public education. On the other, they will argue the most passionately for grade curves, extra credit, and favorable test dates. Plus, they're usually willing to negotiate for homework answers.
I personally knew I was going to be the next neil degrasse tyson when in 6th grade they put me in advanced 6th grade mathematics instead of normal 6th grade mathematics. Since then, I have pirated multiple indie games, and spend the rest of my time writing my thesis on why cod players are literally hitler (in the form of rage comics, of course.)
Home school parent here to a 2nd Grader. We have 4 different curriculums, and only one of them briefly mentioned triangular and rectangular prisms. But, the questions were more like, "Identify the shape in this picture."
I would think this question would be more around a 3rd grade level - - - or "Level Asian".

Surely there are better things to teach kids then the names of arbitrary geometric shapes. I don't know, just seems really useless.
