This lesson provides an opportunity for students to investigate the relationship between perimeter and area. Students begin by creating as many unique rectilinear shapes as possible from five squares to determine the maximum and minimum perimeter, moving on to six and so on once the results are recorded.
Differentiated Learning Objectives
- All students should be able to calculate a perimeter by counting the distance around a shape.
- Most students should be able to calculate a perimeter through the use of short multiplication as opposed to repeated addition.
- Some students should be able to recognise that a fixed area can have multiple perimeters.
