Perimeter and Area - Perimeter of Rectangles - Worksheet

Mastering the concept of perimeter is essential for Year 6 students, and a particular lesson is dedicated to the measurement and calculation of the perimeter of rectilinear figures, including squares. The lesson aims to teach students how to measure perimeters in both centimetres and metres. To facilitate learning, differentiated worksheets and teaching slides are provided as resources. The key vocabulary for the lesson includes terms such as perimeter, rectangles, rectilinear figure, centimetres, metres, length, width, efficient, and integers. Students will practice calculating the perimeter of rectangles that are not laid out on a squared grid, using the lengths and widths provided. They will explore different methods of finding the perimeter, such as adding all sides together or doubling the sum of length and width, and will use their understanding to calculate missing lengths and investigate possible perimeters for squares and rectangles.

The worksheets encourage children to apply their knowledge in a variety of ways. For example, they may be tasked with finding the perimeter of rectangles using given measurements, or they might have to deduce missing lengths to complete the perimeter calculation. The activities cater to different levels of ability, with some students working with 1-digit numbers, while others tackle 2-digit numbers, half centimetres, and a mix of millimetres, centimetres, and metres, including decimals. Students will need to convert between units to find the perimeter in the unit specified. The lesson also includes reasoning and problem-solving questions that challenge students to think critically about the properties of rectangles and squares, such as whether a rectangle with integer-length sides can have an odd perimeter, and to provide proofs and examples to support their answers.
