A lesson introduces the students to pi. Students work out for themselves with little guidance that pi is approximately 3 or even 3.1.
This also gives the teacher the opportunity to introduce the formula for the area of the circle.
The follow up lesson also on this resource has several examples involving finding the areas of circles.
The resource also contains a worksheet for students to answer either in class or as a piece of homework.
