How should students be graded? Most grading systems focus on where a student ended up rather than the progress a student made. As a result, a student who goes from a 100 to a 95 will get an A, while a student who goes from a 40 to a 60 will still fail.

In this lesson, students use percent change to evaluate how changes to a grading policy would affect students and discuss the fairest way to balance mastery with effort.

Students will

  • Convert a fraction to a percent
  • Calculate the percent increase/decrease

Before you begin
