Perimeter of composite re worksheet

In this engaging worksheet, students are tasked with exploring the concept of perimeter through a series of hands-on activities. The first activity encourages children to work in pairs on squared paper to investigate whether rectangles with identical areas also have the same perimeters, with an alternative option to use rectilinear shapes for added complexity. This sets the foundation for understanding the relationship between area and perimeter.

The subsequent activities delve deeper into practical measurement. Students are provided with a variety of measuring tools, such as rulers, metre sticks, tape measures, and trundle wheels, to measure the perimeter of diverse items, which range from everyday objects like an exercise book to larger spaces such as the school hall or playground. This includes rectilinear shapes and items with different units of measurement, enhancing their ability to apply appropriate measurement units. Further activities involve drawing rectangles with a given perimeter on squared paper and exploring different configurations with the same perimeter. The worksheet progresses to more challenging tasks where students calculate perimeters of pre-prepared shapes, some with mixed units and others with missing lengths. The final activity is a creative exercise using squares to form shapes with the largest and smallest possible perimeters, which can be varied by changing the number of squares or the length of their sides. Through these activities, students aim to achieve the objective of measuring and calculating the perimeter of composite rectilinear shapes in centimetres and metres.
