It was definitely not due to wordy responses. The teacher used his homework and 2 other kids journals as examples of what she expected before the change.The class was allowed to take a peek at them if they wanted to. She left them on a table in the back of the room so the kids could randomly peak without being singled out.
My son told me yesterday that many of the kids were not doing the majority of the homework and the teacher had a talk with the class about the importance of reading every night and answering the questions daily.

He asked me to write a note asking if he could do both. I told him he needs just ask her this morning. I hope he does. : )
