I've been meaning to post about this for a couple of weeks, but time has slipped away from me. Anyhow, please check out the blog, Open Wide, Look Inside.
This is Tricia Stohr-Hunt's (The Miss Rumphius Effect) blog that features a wealth of resources that primarily include recommendations for children's books that can be used across math, science, and social studies curricula.
Starting at the end of August and running into mid-November, Tricia's preservice teachers are posting tons of book reviews (more than 100!) and teaching recommendations teachers can use for science and social studies classrooms.
