This resource is a perfect way to engage students in nonfiction texts at a first or second grade reading level. The books are informative, inexpensive, and feature full color photographs. This unit uses the following National Geographic Level One Readers: Polar Bears, Weather, Ants, Frogs, and Trains. There are forty-five pages of activities in all. Each unit contains nine pages of activities: ABC order, comprehension, bingo, memory vocabulary cards, a play for students, reading sentences, a table of contents activity, and a letter writing activity with directions. You could use one book, with the whole class and a document camera, two books for partners or several books for a small group study. This is an excellent way to provide more work for students on nonfiction material.
