This simple bar graphing activity is a great extension for any baseball unit or graphing math lesson. Students create a bar graph for Hank Aaron and Barry Bonds, using 2 year periods in their careers to see how they hit home runs at different points. A table is provided with all numbers. Students then answer questions, including the controversy over steroids in baseball as a final hook. This practice is engaging and for teachers adding baseball into the classroom, this is an authentic use of statistics for formative assessment.
