I enjoyed learning about how to use primary sources to enhance a picture book read aloud. I appreciated how the presenter took us through a mock lesson and had us view a primary source, made the connection to the picture book and then read aloud a bit of the book to give us a taste of how to structure a lesson. I'm using this strategy with my 4th graders right now. I showed them an image of an advertisement for the Macy's parade from 1933 and asked what they noticed. We had a discussion and them read Balloons Over Broadway: The True Story of the Puppeteer of the Macy's Parade.
