The Roaring Twenties Preview Collage is an assignment I use to introduce the US History unit on the 1920s. Students use the web to search for and preview topics that will be covered in the unit--Prohibition, Political Corruption, Jazz Age, The Harlem Renaissance, etc. They will then create a collage of primary source images.
This is a fun activity that gets students excited to learn more about the 1920s.
Update: I added two student samples to this document
