We know that writing a full DBQ essay might be challenging for middle-school students. This optional assessment can be adapted in a few ways: 1) Have students focus on the prewriting exercise, modeling how to unpack the prompt and write a claim. You can use the table on page 2 of the Claim Warm-Up activity to help students parse the prompt and craft their claim. 2) Create learning stations for student groups to examine a smaller selection of the DBQ sources and decide how each source helps to answer the prompt. 3) Shorten the essay in the writing activity to a paragraph or have students create a different product, such as a Google Slide or infographic.
