Lesson details
Key learning points
- When problem solving, consider whether any elements are familiar from other areas of maths.
- Keep the goal in mind, it is easy to get distracted by too much information.
- With diagrams, it can be beneficial to add information to them (such as extra lines).
Keywords
Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Compound shape - A compound shape is a shape created using two or more basic shapes.
Composite shape - A composite shape is an alternative for a compound shape.
Common misconception
When finding the perimeter of a rectilinear compound shape, pupils might sum the perimeters of each rectangle.
Part of the perimeter for each rectangle is inside the compound shape. Therefore, not all of the perimeter of each rectangle contributes towards the perimeter of the compound shape in this problem.
