Max Maths, Year 6, Learn together, Review of perimeter and area (1)

In the Max Maths Year 6 curriculum, students review the fundamental concepts of perimeter and area. The lesson begins with a reminder that the perimeter is the total distance around the edge of a two-dimensional shape. For a rectangle, the formula to calculate the perimeter is given as twice the length plus twice the width, which can be written mathematically as (2 × length) + (2 × width). This formula takes into account both the length and the width of the rectangle, which are the distances of the opposing sides of the shape.

When it comes to a square, where all four sides are equal in length, the calculation is simplified. The perimeter of a square is found by multiplying the length of one side by four, expressed as 4 × side. This accounts for the fact that each of the four sides of a square is of equal length. Additionally, the lesson covers composite shapes—shapes that consist of two or more simple shapes combined. The perimeter of a composite shape is determined by adding together the lengths of all its sides, ensuring that every edge is accounted for in the total perimeter measurement.
