A demonstration of the difference between clockwise and anti-clockwise using dancing and animation. The dancers are moving inwards, outwards, round and round. The dancer moves her ribbon clockwise and anti-clockwise. If you move in a circle in the same direction as the hands of a clock, this is clockwise. If you move in the opposite direction, this is anti-clockwise.

Use the clip to revise the meaning of clockwise and anti-clockwise. This could then be extended to include angle as a measure of turn in different directions eg 90 degrees clockwise and anti-clockwise.
