The workbook "Area and Perimeter" encourages students to practice calculating perimeter by adding the lengths of all sides of various polygons, primarily focusing on rectangles and simple composite shapes. Students practice calculating area using formulas like length times width. The teacher should incorporate activities that involve counting unit squares, using grid paper, and solving real-world problems to reinforce these concepts. Additionally, discussions should include comparing the concepts of area and perimeter and exploring how different shapes can have the same perimeter but different areas and vice versa.
