I am always reading the posts on ProTeacher, but I never post. I enjoy reading and learning from all the wonderful ideas from everyone. Now I need some advice. I am having an observation in the next couple of weeks. I am just finishing up a unit on Exploration and Columbian Exchange. Now I need something introductory but impressive for both the students AND the observer related to a Renaissance unit. I would appreciate any suggestions and units/resources/ideas that you have used and have been successful with. Oh...by the way I teach Middle School students. Thank you for sharing!
