Students learn how make approximations by rounding numbers to one significant figure.
As learning progresses more able students learn how to estimate the solution to problems involving square and cube roots.
Differentiated Learning Objectives
- All students should be able to approximate a product by rounding each number to 1 significant figure.
- Most students should be able to make and justify approximations by rounding to a significant figure.
- Some students should be able to make and justify approximations of square and cube roots.
