This is a nonfiction book from the Pebble Plus series. I love these over sized books. In this particular book, the readers will learn all about the Air Force. The Air Force’s purpose, jobs, tools and machines are all explained in English and Spanish. On each facing set of pages, there is an over sized photo and then text in English and then Spanish. The text is easy and to the point. I really like these English/Spanish books. I love the idea that an ESL student can take it home to read with their parents. Developing students with a Spanish language background can easily see the two languages together on the page. The photos and information are all well developed, as well.
