Measurement Length and Perimeter - Perimeter of Rectangles - Worksheet

The worksheet titled "Perimeter of Rectangles" is designed to help Year 6 students master the concept of measuring and calculating the perimeter of rectilinear figures, including squares, in both centimetres and metres, in line with the National Curriculum objectives. To facilitate learning, the worksheet offers differentiated sheets and accompanying teaching slides. The essential vocabulary for this lesson includes terms such as perimeter, rectangles, rectilinear figure, centimetres, metres, length, width, efficient, and integers. Students are tasked with calculating the perimeter of rectangles without the aid of a squared grid. They explore two methods to find the perimeter: by adding all sides together or by adding the length and width and then multiplying by two. This exercise enhances their understanding of perimeter, enabling them to calculate missing lengths and investigate potential perimeters for squares and rectangles.

The worksheet progresses to more challenging tasks, where students must find missing lengths to determine the perimeter, working with various units of measurement including millimetres, centimetres, metres, and involving decimals. These activities require knowledge of unit conversion. Reasoning and problem-solving questions encourage deeper thinking, asking whether a rectangle with integer length and width can have an odd perimeter, and providing scenarios for students to deduce possible dimensions of rectangles within given perimeter ranges. The worksheet also includes answers for self-assessment. These exercises are designed to develop fluency and precision in calculating perimeters, with tasks segmented into categories such as 'Working Towards', 'Working Within', and 'Greater Depth' to cater to different levels of student proficiency.
