Rounding to Significant Figures

 

Students use place value to round a number to a significant figure.

As learning progresses, they are challenged to approximate square and cube roots.

Differentiated Learning Objectives
  • All students should be able to round a positive number, greater than one to one significant figure.
  • Most students should be able to round any number to one or more significant figures.
  • Some students should be able to calculate the limits of accuracy when a number has been rounded to a significant figure.
