No Name?

There are so many kids in high school that just don't do their homework. Of course their grades show it too. But what doesn't make sense is how many do their homework, get an "A" on it, yet don't have enough sense to put their name on their paper. This is from a math class that Grace is a T.A. in. From the first of school till now none of these papers have a name on them. The board is actually bigger than the pic. Crazy kids!!
