This is an arts integrated and writing intensive project. I used this for my U.S. History Honors classes to give them a break from reading historical documents.
The project divides the class in 3 groups: JFK, LBJ, and the Vietnam War group. Each group has several topics to divide among themselves. This worked well with classes of 30.
The goal is for each group to make a giant poster that is essentially a quilt of the different topics. The assignment has students research and write a paragraph to help them present their topic to the class. Then after researching and summarizing their section they make a poster for it.
Each group will have several posters to staple together. Students had a lot of fun trying to manage these hilariously large posters in front of the class.
Walk the class as students work. This is a fairly structured project, and expectations should be clear at this point in the year as to what your own expectations are for their quality of work.
This project is easily tweaked to go along with your specific textbook or curriculum. This is aligned to Florida State Standards on the 60s and 70s.
