              Using equivalent ratios students learn how to work a percentage change in reverse to calculate the original 100% value.  As learning progresses they are challegned to apply their learning to solve real life problems in context.
              Differentiated Learning Objectives
              • All students should be able to calculate 100% when given a representative percentage change.
              • Most students should be able to calculate the original value after a real life percentage change.
              • Some students should be able to calculate the original value after a compound percentage change.
