Each content chapter opens with a brief introduction that encourages students to preview important ideas and terms they will encounter in the chapter. The opener acts as an advance organizer to set the tone of the historical time period explored. This helps students to organize the content into information that they can more easily assimilate. The opening page includes pictures, a brief overview of the chapter, and a graphic organizer, providing students with an advance organizer that highlights the Key Idea, Conceptual Understandings, and events explored in that chapter. Visual learners benefit when content material is presented in graphic form.
