Solving Problems about Percent Increase or Decrease

Open Up Resources 40 min(s)

Solve word problems leading to equations of the form or px + q = r p(x + q) = r. Let's use tape diagrams, equations, and reasoning to solve problems with negatives and percents. Learning targets: students can solve story problems about percent increase or decrease by drawing and reasoning about a tape diagram or by writing and solving an equation. Decide if students will conduct group presentations or a gallery walk for the last activity. If so, prepare tools for creating a visual display and around 3 sticky notes per student.
