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.
