I use this form with my first graders to help them really "dig" into nonfiction books. I usually do a mini lesson using a big book and this form up on the smart board to fill out as a class. I then have students(that are ready) practice filling this out with nonfiction books during my small group lesson with them. Then I will make this independent work for those who are ready. This could easily be modified for use all the way up to 5th grade.
