# Maths KS2: As The Crow Flies

**We demonstrate how to calculate the perimeter and area of simple and compound shapes.**

The importance of using correct units in measurement is emphasised via the increasing annoyance of the Measuring Crow.

We also give the formula for the area of a triangle.

This clip is from the series Kick Sum Maths.

*Teacher Notes*

*This clip can lead to discussion of what may go wrong if we don't write down our units while calculating area and perimeter.*

*Also, what operations make sense when dealing with units? For example, does metres + metres squared makes sense? What about metres x metres squared? Or pounds (£) per metre? Metres per pound?*

*Curriculum Notes*

*These clips could be used for teaching Maths at KS2 or at a beginner level in England, Wales and Northern Ireland and 1st and 2nd Level in Scotland.*
