A group of students designs card displays for football games. They use 100 square cards for each display. Each card contains part of a picture of a message. At the game, 100 volunteers hold up the cards to form a complete picture. The students have found that the pictures are most effective if the volunteers sit in a rectangular arrangement. What seating arrangements are possible? Which would you choose? Why?

Simplify the following expressions:
12 + 8h – 6h =
9a + 1 -3a =
7 + 4k – 2 – 2k =
15x + 8 – 10x -3 =

That's one of the biggest problems I have. The kids can't do the problem not because they don't have the mathematical chops but because they can't fscking read!
Granted, that is also an issue, but I'm sick of my kids getting slammed in math for issues that have nothing to do with math.
If the "math" department downtown had any idea how much of this pile of useless flotsam I leave out of my lessons...
And to top it all off, the Singapore Math stuff looks exactly like assignments I write on my own to give them as "supplements" (i.e. the real math they should be learning).
I don't get the Connected Math question. It sort of ignores logic. If the cards have to impart a specific message that depends on putting the cards together in a specific way to read that message, shouldn't there only be one possible arrangement?
I can bet you that my grade 6th self would be utterly confused and convinced this was some kind of trick question.
I wonder what the point of the CM problem is? Showing combos of widths and lenghts to point out that perimeter can be the same with various widths and lengths?
I think the problem is difficult for anyone who hasn't the cultural background of seeing the card pics on TV or live in person.
lgm, good point! What ever happened to multi-cultural math>
