Take a minute to explore the teacher resources (lesson plans, themed resources, primary source sets, presentations and activities, and collection connections): http://www.loc.gov/teachers/classroommaterials/
Keeping in mind the LOC is in our "neighborhood," it is interesting to point out there is a field trip program designed for 4th to 6th graders titled "The LOC Box Program." Students complete the LOC Box activities to “unlock the secrets” of the historic Thomas Jefferson Building and learn about the Library of Congress and its resources. They must use four key skills: observe, analyze, communicate, and investigate. Working in small teams led by adult chaperones, students participate in hands-on activities such as drawing, solving puzzles and mosaic-making. The program provides take-home materials with additional activities to encourage the students to explore the Library’s online resources from home or school and to return for a visit with their families. More information can be found here: http://www.loc.gov/visit/tours/groups/locbox/
To give you a sense of some of the resources, following are four of the units that can be found in the "presentations and activities" section:
If you'd like to explore Inaugurations through history, take a look at this module. Note that the picture of JFK was taken in front of our Lower School. Our own little piece of inaugural history
This might be an interesting element of the decades project...
Let me know if we can help you locate any additional resources from the LOC!
