Learning Intention: Students will understand the difference between area and perimeter and that if you double the area of a paddock, you do not necessarily double the perimeter.

Success Criteria: Using a fixed quantity of fencing, students will model different areas of paddock. With a fixed area of paddock, students will find different perimeters.

A farmer has 3.6 kilometres of fencing. Convert to metres and design five different paddocks using all the fencing. Calculate the area of each paddock. Which has the greatest area?

A farmer needs a paddock of 2400 metres square. Design four different paddocks with this area. What is the perimeter of each of these paddocks?
