Perimeter - PowerPoint

Teaching resources for Year 5 maths classes include a comprehensive PowerPoint on perimeter, a fundamental concept in measurement. The presentation illustrates the simple process of calculating the perimeter of a shape by adding up the lengths of all its sides. For example, a shape with sides measuring 3m, 1m, 2m, 3m, 2m, 1m, 3m, and 5m has a total perimeter of 20m. Students are encouraged to measure the perimeter of various shapes presented in the slides, enhancing their understanding of how to apply this method in different scenarios.

In addition to the PowerPoint, there are worksheets available for students to practice measuring perimeters. These worksheets involve a range of shapes, such as rectangles and irregular hexagons, where students are tasked with calculating or measuring the perimeters. The activities also include creative challenges where students use graph paper to draw shapes with specified perimeters, such as a rectangle with an 18cm perimeter or a square with a 12cm perimeter. This hands-on approach helps students visualise and better grasp the concept of perimeter. Furthermore, there are problem-solving exercises where students must find missing lengths given the total perimeter, offering an opportunity to apply their knowledge to more complex problems.
