In this lesson plan, students will begin an engagement activity where the teacher shows an image of the Washington Monument and students will be asked it's symbolism. Then students will take a gallery walk of images and discuss what they see or have read and record their information on a worksheet. The teacher will introduce the terms “primary source” and “secondary source” along with the definition for each. The teacher will share examples of both primary and secondary sources and engage students in conversation about the examples. For a review of the lesson, students will be divided into groups of 3 or 4, and each group will be given a deck of cards (source examples) and sort them into primary source or secondary source categories. As a closing, students will discuss how they categorized their cards and to check for understanding of the lesson, students will complete an exit ticket.
