Primary Source Task Cards based of the Library of Congress' worksheet of the same. These work well in stations/cooperative learning with task cards for audio/visual, image, map, and document sources. Each card has 3-4 questions on it. You can use them in stations or as prompts to get you started. Students can inquire into a source or the teacher can provide the sources.
Students could be given a card and a primary source to research and then answer their questions. Students can work in pairs, small groups, or independently.
