Write a page about your picture and paste it on the back. Imagine you are in music room at Montauk. See if you can find sheet music or recordings of popular music from back then and play them in class. Keeping a scrapbook was a popular pastime for children and adults during the Larrabee's time. Scrapbooks can contain just about anything you want to remember.
Some people make scrapbooks about their families, their hobbies, or newspaper articles of interest.
Make your own scrapbook. Share it with your classmates. The Larrabees' raised their own children in the 1860s to 1800s, then raised some grandchildren at Montauk after 1900. See if you can find out about these changes at your public library. Write and perform a short play comparing how children were raised then with how they are raised today.
