Earliest recommended Year group: Year 10.
Imagine you needed to remove one metre depth of topsoil from a new building plot. What volume does this represent? How many wagons will you need, etc? By approximating this area to a polygon (where you know the coordinates of the vertices) makes the task very easy (even easier with a spreadsheet).
This is from the “Something in Common” collection of resources by John Burke. They allow consolidation of key skills, prevent students from copying each other (as all the questions are different), make marking and assessing easy for the teacher (as all the answers are the same!), and provide a lovely extra challenge for students as they try to figure out exactly what is going on!
