According to the College Board's Course and Exam Description, "A fitting test of overall student understanding could be to ask students to identify the most significant developments within each theme as it applies to each period of the course" (p. 106). With that in mind, the following activity uses digital timelines to review thematic content across the six time periods of the course. It is intended as a review, not as an exhaustive encyclopedia of content. Each theme is broken down into a few salient topics to better focus the review. To get the most out of this, you should download and complete the Graphic Organizer for each timeline and then test your knowledge with the online quiz. Each timeline has links to enrichment materials.
