 So it's a week-long program that we've done Monday through Friday. This year we will be adding an evening portion on Sunday just to kind of give an overview of the Civil War so that everyone's on the same page and comes with the same background knowledge. But each site has their own day. So they start at Tudor Place on Monday and we kind of bring, Tudor Place, the person that lived in the house was named Britannia so we kind of try and bring that women's history as well as the history of the enslaved Africans and then free Africans who they hired after the Civil War in that perspective. On Tuesday they visit Frederick Douglass House. We actually have a Frederick Douglass interpreter who talks about auditory and how people can use auditory to further movements. Lincoln Cottage would be on Wednesday to kind of give the early years of the Lincoln's presidency and his trips out to the cottage. And then we end chronologically with Ford's Theater with the assassination of Lincoln. And we leave Friday open so that gives teachers time to process, reflect, and actually then start to create a lesson or some sort of activity that they can then bring back into their classroom. And each of the days we stress both contents or trying to provide teachers with enough information on the Civil War for them to feel comfortable teaching it. But our main goal is to teach techniques so ways you can, we model the techniques for teachers on how to bring primary sources into their classroom. And we really encourage teachers, we introduce teachers to the backwards planning template early in the week and we ask them to use that template in concert with their local standards as the way to develop their program, whether it's a unit or a field trip or whatever else. Because we want to be modeling what we consider best practices. And it's very interesting, many teachers are not comfortable with the backwards planning template asking them to think first about goals and standards and then about objectives and assessment and then moving into activities. But they become more comfortable with it over time. And for us it's okay for them to be struggling with that during the week because it's a big part of learning how to engage productively with content.
