Lesson 7
Revisit Percentages
Lesson Narrative
Students learned about what percentages are and how to solve certain problems in an earlier unit. At the time, they did not learn an efficient procedure for finding \(B\) in “\(A\%\) of \(B\) is \(C\)” given \(A\) and \(C\), because they didn't have an efficient way to solve an equation of the form \(px=q\). Now they do, so we briefly revisit this type of problem.
Learning Goals
Teacher Facing
- State explicitly what the chosen variable represents when creating an equation.
- Use equations to solve problems involving percentages and explain (orally) the solution method.
- Write equations of the form $px=q$ or equivalent to represent situations where the amount that corresponds to 100% is unknown.
Student Facing
Let's use equations to find percentages.
