Calculating Area of Rectangles and Squares

This lesson teaches how to calculate the area of geometric shapes, specifically squares and rectangles. It begins with an introduction to the concept of area, using a square as an example. The lesson explains how to determine the area by counting square units and introduces the formula for area calculation: length times width. The lesson then applies this formula to a rectangle, demonstrating the calculation process step-by-step. By the end of the lesson, students will understand how to calculate the area of both squares and rectangles using the formula.
