J.,
As a teacher, I'm going to suggest that you talk to the teacher. If you haven't spoken to her, you haven't been fair, nor have you expressed your daughter's needs or helped her express her feelings.
Has your daughter spoken to the teacher about not feeling challenged? Does she complete the classwork quickly and accurately? Is she SHOWING the teacher the work is too easy for her? Showing is the best way for a teacher to know, if you're not telling.
I teach 4th Gr. and I expect my students to talk to me about their issues, problems, struggles, joys, etc. They do. I realize they are a year older, but if your child is truly bored, maybe she could speak to the teacher about not feeling challenged.
About reading "baby" books, while I teach 4th Grade (Gifted classes in a school for only gifted students), I often read picture books to my students. In fact, last year I read Carl Goes to Daycare to 40 gifted 9-11 year olds. This was a lesson about details and perspective. It was also a lesson about how we expect more of them as writers as they grow (I read my 3 year old daughters version of the story, which was quite eloquent if I say so myself.). We then followed up the lesson by reading The Arrival, another picture/graphic book, for the writing assignment (put words to the pages/pictures). The teacher could be doing an author study (Patricia Pollacco is great for that.), providing background knowledge, teaching mini lessons that will serve them through out the year in Readers' Workshop, etc. Any number of reasons for the books she's reading. Did you ask?
At a minimum, you NEED to talk to the teacher. Stop talking about the teacher to parents and other teachers. It just stirs up a pot of bees. As my daughter witnessed last year, the one who stirs up the bees doesn't always get stung;sometimes it's the innocent by-stander.
Talk to the teacher.
