This teacher guide introduces students to the concept of area, defining it as the space within a boundary of a two-dimensional shape or flat surface. It includes learning targets such as calculating the area of rectangles, triangles, and parallelograms using standard formulas, applying these formulas to solve real-world problems, and connecting the concept of area to situations like interior design. The document emphasizes the measurement of space using square units and provides materials needed for classroom activities, setup instructions, and practice problems. It also discusses common mistakes in area calculation, features various teaching strategies including group activities and real-world applications, such as planning a carpet installation, and culminates with an exit ticket challenge that requires calculating the area of a triangular flower bed and determining associated costs.
