# Estimating Solutions by Rounding

Students learn to estimate solutions by rounding numbers to a significant figure.

As learning progresses, students also consider approximations of square roots and use 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.
