Learning goals: Teacher Facing Choose and create diagrams to calculate A% of B, and explain (orally) the solution method. Generalize a process for finding A% of B and justify (orally) why this can be abstracted as $\frac{A}{100} \boldcdot B$. Identify equivalent expressions that could be used to find A% of B and justify (orally) that they are equivalent.
