Rounding to Significant Figures

Students learn how to round a number to a significant figure using number lines and place value.  As learning progresses they are challenged to approximate square and cube roots.  An interactive Excel file and Tarsia activity are included in order to provide additional consolidation.
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.

Calculating the Volume of a Pyramid

March 10, 2019

When calculating the volume of a pyramid we can substitute the values of the length, width and perpendicular height into the formula V = 1/3 lwh.  In my experience this is often provided for the students with little explanation as to why a volume of a pyramid is exactly one third the volume of a […]
