Have you taken a look at Scholastic's Common Sense for the Common Core site? There's a lot of really useful information there for parents. One of their newest pages is the Nonfiction & Literature Lists that makes book suggestions based on a child's grade and subject matter.
I was especially pleased to see multicultural books included in the lists. So if you are looking for a good resource to help develop your child's reading abilities with materials that are common core aligned, be sure to check out this great page.
