I put a plea out on facebook to see if anyone could send me a picture of the page and was thankful that a friend of mine obliged. (He was too, considering that the punishment for not having an assignment is 50% off and having to sit during recess. Grr.)
I normally don't check over his assignments too closely because he does so well, but because I was copying from a picture that my friend sent onto a separate sheet of paper I obviously knew exactly what the problems were.
#1 - 4 were multiplication.
The next section went to this:
(Point E was drawn in by my friend's son.)
My guess is that they were working on plotting points.
The page finished up by asking the students to plot Point E so that BDEC was a square. (FYI, my boy was able to do it correctly. :) )
And the kicker? Find the area of the square.
This caught me off guard. I don't think the kids have done Pythagorean Theorem or (most definitely) the Distance Formula. So when my boy looked at me with a blank look on his face, I decided I'd talk him through it.
I started by asking him what shapes he knows how to find the area of. The answer? A square/rectangle and a triangle. We drew a big square around BDEC so that he could see some extra triangles. He figured out that the big square was 5 x 5 and each triangle had a leg of 1 and a leg of 4. Taking the area of the big square minus the four triangles, he ended up with area 17.
I followed up the next day and asked how his math had gone (I basically wanted to make sure that she accepted the homework even though he'd written it on a different piece of paper.) The first thing that he told me was that "my" answer of 17 for the area was wrong. It was supposed to be 16.
Um, what?! [You know what she did, though, right?]
I tweeted it. (Of course.)
I was happy that everyone agreed with me. And Mike Lawler even YouTubed his son solving it!
(Check out Mike's blog here!)
I sent the video to my son's math teacher (thought it would be a nicer way than saying nyah nyah nyah) and haven't heard anything back. [I did put it nicely; said it was such a great problem that I tweeted it and this guy made a video!]
