Sometimes during the high school years (grades 9-12), kids have to study United States History if you live in America. If you’re looking for a free option, I found these printable worksheets. There are 167 total worksheets that are in chronological order and divided into 15 sections. Each handout includes an informational reading followed by a series of questions based on the reading. These are quick and easy lessons to add to a curriculum, unit study or as a springboard for related activities.
