I love this activity by Bruce Ferrington with his students.
What Is My Area?
Wait – before you say anything – I know your body is 3-dimensional and area is a measurement of two dimensions – so I probably should say, “What is the area of my silhouette?”
What is the area of my silhouette?
In the past week we have measured height and width, talked about Vitruvian Man, combined our heights, compared them with other classes.
Time to have a look at comparing areas.
My chief interest here is to look at how the kids are going to approach this question. I want to see if they can come up with any short-cuts that will speed up the calculations, so they don’t have to cover their entire body in 1cm grid paper and count out each square.
