Here are some site I recently found for my 9yo to do a unit on castles with his dad over the summer. http://score.rims.k12.ca.us/activity/castle_builder/ THis is a great lesson plan that has the student do a lot of research in order to build a castle to the Baron's specifications. It is well laid out and has some good links already in the lesson plan. THis is the lesson plan that I am going to have our son follow with his dad's help. THere are some additional castle sites http://www.castlesontheweb.com/ http://www.wizards.com/default.asp?x=dnd/fpm/archive http://edsitement.neh.gov/view_lesson_plan.asp?id=448 http://www.fiddlersgreen.net/buildings/castle/castle.htm http://www.papertoys.com/ http://www.fryerskits.com/trebindex.htm I hope that helps anyone doing a unit on castles or middle ages studies.
