This math topic focuses on identifying the correct formula for calculating the area of different simple shapes. Students are presented with images of geometric shapes and must choose the appropriate method for finding the area from multiple choice options. The methods include: "half the base times the height" for triangles, "side times side" (implying squares or other quadrilaterals with equal sides), and "length times width" typically used for rectangles. This basic exercise helps build foundational skills in understanding area calculations for different simple geometric shapes.
