Learning Goals

  • Critique or justify (orally) statements about percentages and equivalent numerical expressions.
  • Generalize a process for finding the percentage that C is of B and justify (orally) why this can be abstracted as $\frac{C}{B} \boldcdot 100$.

Student Facing

Let’s find percentages in general.

Learning Targets
