              Estimating Solutions by Rounding

              Students learn how to estimate solutions by rounding numbers to a significant figure.  As learning progresses students also consider approximations of square roots and using the order of operations to break calculations down.
              Differentiated Learning Objectives
              • All students should be able to estimate a solution by rounding each number to one significant figure.
              • Most students should be able to estimate a solution by rounding each number to one significant figure and the nearest square number.
              • Some students should be able to estimate solutions using a combination of rounding to the nearest significant figure, square/cube number or square root.
