So I'm putting you to the test: Can you pass Older Girl's math final? I'll just give you a sampler of the material, and you can leave the answers in the comments. I don't have a prize, but you'll have the knowledge of your mental superiority to keep you warm at night. I'll post the answers later this weekend, if you dare to participate . . .
- Give two reasons why a triangle and a rectangle are not congruent.
- Identify the solid figures:
- I have no flat surfaces, vertices, or edges.
- I have two flat surfaces that are circles. You can roll me.
- I have 6 flat surfaces. They are all squares.
- I have 6 flat surfaces. 4 of these surfaces are rectangles.
- A cube has ___ flat surfaces, ____ vertices, ____ edges
- I have more than 8 edges. Only 2 of my faces are squares. What am I?
- One of my flat surfaces is a square. I have 5 vertices. What am I?
Good luck, Mathletes!
* Give two reasons why a triangle and a rectangle are not congruent. hold on, let me go look up the definition of congruent...
ReplyDelete* Identify the solid figures:
* I have no flat surfaces, vertices, or edges. You are a sphere
* I have two flat surfaces that are circles. You can roll me. You are a cylinder.
* I have 6 flat surfaces. They are all squares. You are a cube
* I have 6 flat surfaces. 4 of these surfaces are rectangles. You are a refrigerator box.
* A cube has __6_ flat surfaces, ___8_ vertices, __8__ edges
* I have more than 8 edges. Only 2 of my faces are squares. What am I? You're still a refrigerator box.
* One of my flat surfaces is a square. I have 5 vertices. What am I? You are a pyramid.
I am probably not as smart as a 2nd grader. Looks like I'm not meeting Jeff Foxworthy soon.
WOW! I am thoroughly impressed she is learning this stuff in 2nd Grade! My daughter did not learn ANY of this this past year! What is wrong with our school??? WOWOWOWOWOW!
ReplyDeleteI don't know this stuff. I probably wouldn't make it out of kindergarten. I was always horrible at math. Looking at Amy Giglio's answers it all makes sense and seems so easy, but I couldn't have done it without cheating.
ReplyDeleteCan't wait to see the real answers!
ReplyDeleteYAY Euclid! (yes, I wear my nerd sign with pride ;-) )
So, here's my attempt...
- they have different # of sides and vertices; therefore they would not align when overlayed
-sphere
-cylinder
-cube
-right square prism
-6,8,12
-right square prism
-pyramid
ooh, Johanna- Prism! I forgot about prisms!
ReplyDeleteWhat is this girl's teacher trying to do to them giving them two questions with the saame answer. I always hated when teacher did that. It's tricky. I always had a suspicion that one of them had to be wrong.
Yeah, well, apparently second grade is harder than I remember!! I help with homework nightly and don't cheat using the parent guide, either.
ReplyDeleteI was about to comment, "What's a 3-D rectangle thing called?" But I see that Amy Giglio has already given the answer: it's a refrigerator box.
ReplyDeleteBut I still don't know what congruent means.
