Can You Pass Second Grade Math?

I think maybe Older Girl has surpassed me in Math knowledge. She came home with a 100! on her Math final (finals! in second grade!), and I knew that my days of helping her with her 'rithmetic were quickly drawing to a close. I'm all right with that, because I'll totally knock it out of the park when she gets to essays and comparative lit, but I still feel pretty lame. I do know this stuff, but I was appalled at how long it took me to answer them. I may need summer school.

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!

  1. * Give two reasons why a triangle and a rectangle are not congruent. hold on, let me go look up the definition of congruent...
    * 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.

  2. 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!

  3. I 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.

  4. Can't wait to see the real answers!
    YAY 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

  5. ooh, Johanna- Prism! I forgot about prisms!

    What 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.

  6. Yeah, well, apparently second grade is harder than I remember!! I help with homework nightly and don't cheat using the parent guide, either.

  7. I 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.

    But I still don't know what congruent means.

Go ahead and say it. You know you want to.
