The document provides instructions for students to solve three shaded area problems of circular shapes with tiles around the edges. For each problem, students are given a scale diagram and asked to explain how to find the area of the shaded region, then calculate the area and include the units. The document directs students to create their own shaded area problem to trade with another group to solve.
