I was at a crossroads trying to think of a new… interesting… active way to introduce and teach the different types of economic systems. I turned to Lesson Planet and entered “Economic Systems” into the search tab and was inundated with resources and lesson plans and ideas… the kids loved the lesson I modified for them and still ask when we are going to do another lesson like that “Paper Airplane Company” one. Thanks Lesson Planet.
