Instead of creating a White House, I am asking the students to research one of the monuments/memorials located in Washington DC. They will then create a model of that monument and present the facts to the class. We will take some class time to research and I have found some really good websites for the kids to use. (I'll post those later.) We also started today by reading a couple of articles about some of the monuments.
Depending on time I may still require the students to do the presidential report. Since this is the first time doing monuments, it is a work in progress. I will keep you posted of any changes along the way.
PS - Don't forget to sign your child's syllabus.
