Lesson details
Key learning points
- Your knowledge of loci can be applied to your knowledge of bearings
- Your knowledge of loci can be used to help solve area problems
Keywords
Locus/loci - A locus is a set of points that satisfy a given set of conditions. Multiple sets of points are referred to as loci.
Bearing - A bearing is an angle measured in degrees from North in the clockwise direction and written with three figures. E.g. an angle of 82° is written as 082°.
Area - The area is the size of the surface and states the number of unit squares needed to completely cover that surface.
Common misconception
Pupils may not consider that, in some contexts (e.g. a corded lawnmower), the shape of the locus will include sectors of different radii, if a shape/object is creating a barrier.
Have pupils consider the impact of going around the corner of a shape.
