Calculating Area of Shapes

Miss Susan guides Grade 4 students through Chapter 13's mid-chapter checkpoint, focusing on understanding and calculating the area and perimeter of shapes. The lesson begins with defining key vocabulary terms such as area, base, formula, parameter, and square unit. Students learn the formulas for area and perimeter and apply them to solve problems involving rectangles and squares. The video includes examples and step-by-step calculations to reinforce the concepts.
