Perimeter and Area - Area of Rectangles - Presentation

In an engaging mathematics lesson focused on the area of rectangles, students will apply the formula 'length x width' to calculate the area of various rectangular shapes. The lesson encourages students to explore the meanings of length and width, and to discuss these dimensions in the context of rectangles. Through a series of activities, they are prompted to consider the properties of rectangles and squares that are necessary to perform these calculations effectively. The lesson aims to deepen their understanding of how to determine the area of these shapes and the relevance of each dimension in the formula.

Students are challenged with tasks such as designing multiple rectangles with a given area and calculating the area of shapes with squares of different lengths. The lesson also includes practical applications, such as determining the total area of gardens in a row of terraced houses or allotment plots, reinforcing the real-world relevance of these mathematical concepts. Reasoning exercises further test their comprehension, asking them to estimate and compare areas, and to investigate the relationship between changing a shape's dimensions and its area and perimeter. The lesson culminates with independent work, where students calculate the areas of various shapes, fostering their ability to work autonomously and apply what they have learned.
