Activity Overview

Before or after studying the United States' territorial expansion, students will want to have a good idea of the sequence of events and the steps America took to increase their land holdings. Using a timeline, students will be able to visualize each event and see how it fits in the narrative of westward expansion.

Students should begin with the Louisiana Purchase of 1803, and note and explain major acquisitions between 1803 and today, such as Florida, Texas, the Mexican Cession, Oregon, and for connective purposes, include the modern acquisitions of Hawaii and Alaska (both of which became states in 1959). Students will be able to analyze and explain major concepts such as manifest destiny, war, foreign relations, and culture.

For an alternative to the timeline layout, have students create a timeline poster to incorporate into a presentation or gallery walk. You can add more than one template to this assignment to give students lots of options, and update the instructions accordingly.
