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.

REAL WORLD TAKEAWAYS

  • What a final grade reflects depends on the grading system used.

MATH OBJECTIVES

  • Convert a fraction to a percent
  • Calculate the percent increase/decrease
Appropriate most times as students are developing conceptual understanding.

Grade 7
Percents & Proportions
Content Standards 7.RP.1 Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units. For example, if a person walks 1/2 mile in each 1/4 hour, compute the unit rate as the complex fraction <sup>1/2</sup>/<sub>1/4</sub> miles per hour, equivalently 2 miles per hour. 7.RP.3 Use proportional relationships to solve multistep ratio and percent problems. Examples: simple interest, tax, markups and markdowns, gratuities and commissions, fees, percent increase and decrease, percent error.
Mathematical Practices MP.1 Make sense of problems and persevere in solving them. MP.3 Construct viable arguments and critique the reasoning of others.
