Area - PowerPoint

In this educational resource, Year 4 students are introduced to the concept of area as part of their maths curriculum. The focus of the lesson is to understand and calculate the area of two-dimensional shapes through a practical and visual method—counting squares. The presentation begins by differentiating between perimeter, which is the total length around the outside of a shape, and area, which refers to the amount of surface space a shape covers on the inside. Students learn that area is measured in square units, such as square centimetres (cm²), and the lesson provides clear illustrations to help visualise this measurement.

The PowerPoint guides students through the process of finding the area of various shapes by fitting as many 1 cm² squares as possible inside the shape. An example is shown where 12 square centimetres fit into a given shape, demonstrating how to write this as '12 cm²'. The resource then encourages students to apply their learning by counting the squares within different shapes to find their areas. Interactive elements are included to reveal the correct answers and reinforce the learning. This hands-on approach helps students to grasp the concept of area in a tangible and engaging way, laying the foundation for more complex mathematical understanding in the future.
