Students are introduced to rounding numbers to a significant figure. Learning progresses from rounding whole numbers from one significant figure to rounding decimals to two or more significant figures. More able students are challenged to find the limits of accuracy for rounded numbers.
Differentiated Learning Objectives
- All students should be able to round an integer to the first significant figure.
- Most students should be able to round a number to a given significant figure.
- Some students should be able to determine the limits of accuracy for a number rounded to a significant figure.
