Here is a nonfiction text resource that includes several worksheets and posters. There is a worksheet on skimming and scanning skills and includes 2 posters.
Nonfiction text cards that you could make as a sort or use to create flip books.
There is also a Nonfiction Scavenger Hunt as well as a Nonfiction Chart that students can fill in as a center or even during a guided reading group.
Happy Teaching! :-)
