@Stealth83 : I still see it as self serving and not kosher for a teacher to be doing at this grade level.
Yes, I had to buy books in high school, Lord of the Flies, The Pearl, Animal Farm, but the teacher did not profit from these purchases. Nor did he get a review to boost his standings. I just had to write a book report on these books.
IF he were asking for book reports, maybe. Positive reviews? Uh, no.
