Here is the most offending paragraph:
***Please note that 5th grade leveled reading books come in various sizes. They can be short novels, long, thick chapter books (Like Harry Potter) and picture books. I advise the students' to only pick a book, they are confident; they can read in the acquired time and can can comprehend.
I assume your child is in 5th grade from the post.
Not only would I be mad that it came from a language arts teacher, I would be upset about it coming from a 5th grade level teacher. My DD just started 5th grade, she has four teachers, and we were told that language arts/spelling would be expected in all subjects and part of those grades.
How can you teach if what you give out is not correct?
