Max Maths, Year 4, Work Book, Perimeter

In the Max Maths Year 4 Workbook, Practice 4 focuses on calculating the perimeter of various shapes. Students are tasked with finding the total distance around the edge of given shapes, which include rectangles and other polygons. For instance, they are provided with the measurements of two sides of a rectangle, such as 5 cm by 5 cm, and are required to determine the perimeter by adding all the side lengths together. The exercises progress from simple shapes with side lengths provided to more complex problems where students need to deduce missing side lengths based on the total perimeter given.

Further exercises in the workbook guide students through the process of calculating perimeters for different polygons. They are introduced to the formulas for finding the perimeter of a square (4 times one side) and a rectangle (2 times the length plus 2 times the width). The workbook also includes practical activities, such as measuring sides with a ruler and solving problems that require a deeper understanding of shapes and their properties. For example, students might be challenged to find the length of missing sides when the total perimeter is known, or to create a six-sided shape with specified perimeter and side length constraints, encouraging them to apply their knowledge creatively.
