Students learn how to calculate the limits of accuracy of rounded numbers.

As learning progresses they are challenged to consider the upper and lower bounds of simple calculations.

Differentiated Learning Objectives

• All students should be able to calculate the limits of accuracy for a number rounded to the nearest power of ten.
• Most students should be able to calculate the limits of accuracy for a number rounded to the nearest decimal place.
• Some students should be able to calculate the limits of accuracy for a number rounded to the nearest significant figure.
