Max Maths, Year 6, Work Book, Perimeters of compound shapes

The Max Maths Year 6 Workbook provides a series of exercises designed to help students practice calculating the perimeters of compound shapes. In Practice 3, students are tasked with measuring the sides of various shapes using a ruler and then adding those measurements together to find the total perimeter. The first activity requires students to measure each side of a given shape and then sum up those lengths to determine the perimeter. The exercise offers a structured approach by providing a formula where students can input their measurements and calculate the total.

In the second activity, students are presented with a shape that has some side lengths missing. They must use the given measurements, such as 14 metres and 4 metres, to deduce the missing lengths and then calculate the shape's perimeter. Additional exercises involve more complex shapes where students need to determine unknown side lengths before they can find the perimeter. For example, students might be asked to calculate the lengths of sides labelled A and B by considering the surrounding dimensions. Finally, the workbook challenges students with a problem-solving task where they must construct their own six-sided shape with a specified perimeter, using given information about the shortest and longest sides. This encourages creative thinking and application of their understanding of perimeters in a practical context.
