KS3 Perimeter of Quadrant, Semicircle & 3 quarters

Calculating circumference of quadrants, semicircles and three-quarters can be a difficult task for young learners. As a primary children teacher, I usually create a colourful visual stimulation presentation to grab their attention. I add colours to make the demonstration more interesting yet informative. Each problem is followed by a clear instruction on how to attain the final answers. You may use this presentation as an introduction lesson and as a classroom game.
