One thing I do as a teacher is during our "Hero" unit at the end of the school year I pick out a military hero for the students to learn about. This year we studied Staff Sergeant Paul Smith of the 3rd Infantry Division and why he won the Medal of Honor during the Battle of Baghdad in 2003. We studied the battle, built a battlefield, and painted up miniatures for the battle. Here are some of the miniatures my students painted up. Pretty good for a bunch of 9 year olds!
All of the terrain was scratch built using materials we had in the classroom.
