Max Maths, Year 5, Learn together, Area (4)

In a Year 5 mathematics lesson focused on understanding the concept of area, students are presented with a practical example involving a school lawn. The lawn is described as having a length of 9 metres and a width of 3 metres. To determine the area of the lawn, students are reminded of the formula for calculating the area of a rectangle, which requires multiplying the length by the width. Applying this formula, the area of the school lawn is found to be 27 square metres, expressed as 27 m², providing a clear and tangible example of the concept of area in a real-world context.

Another exercise challenges the students to find the width of a rectangle when given the area and the length. With an area of 28 m² and a length of 7 metres, students are taught to use division to discover the missing dimension. By dividing the area by the length (28 m² ÷ 7 m), they find that the width of the rectangle is 4 metres. This exercise reinforces the relationship between area, length, and width, and demonstrates that while multiplication is used to find the area, division is used to find a missing dimension when the area is known.
