Classifying and Measuring Polygons

Mrs. Walker introduces polygons, focusing on comparing and classifying them based on sides, angles, and parallel lines. Students are guided through exercises to group polygons by equal sides, identify right angles, and recognize regular polygons. The lesson includes practical activities using rulers and problem sets, culminating in a challenge to identify polygons by specific attributes.
