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?”*

*So…*

**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.*
