How to calculate area in square metres from knowledge of lengths and widths using a real life problem - estimating and measuring the length of a carpet. Common mistakes are accounted for and explained so the children are aware of such errors when using and applying more complex operations in maths.
This clip can be used as part of a lesson on measuring area and, in particular, to help pupils avoid making common mistakes when doing so. Following the clip being shown, pupils can be given their own dimensions, possibly in millimetres or centimetres, for a carpet that needs to be fitted onto their sheet of paper. They can then be asked to work out the area and cut out a piece of sugar paper to the right size. They can then follow the Chuckle Brothers' example to make it fit correctly.
