Area and Perimeter
Notes and Guidance
Children should calculate area and perimeter of rectilinear shapes. They must have the conceptual understanding of the formula for area by linking this to counting squares. Writing and using the formulae for area and perimeter is a good opportunity to link back to the algebra block. Children explore that shapes with the same area can have the same or different perimeters.
What is the difference between the area and perimeter of a shape?
How do we work out the area and perimeter of shapes?
Can you show this as a formula?
Can you have 2 rectangles with an area of 24 cm² but different perimeters?
