This lesson plan outlines a class on why people pay taxes. The class will be taught to grades 9-12 at Lad Lake High School. The lesson will use a slideshow, online activities, group work, and class discussions to help students understand that governments need tax revenue to provide public goods and services. Key learning objectives are for students to describe why governments need revenue, identify taxes as a major source of that revenue, and explain how taxes transfer resources from people to the government. Assessments will include an informal check for understanding and a formal worksheet for students to complete.
