TES Maths ROTW 18 – Equation of a Circle Clock

May 26, 2014 - TES, TES Resource of the Week (ROTW)

Spicing up the post-16 topic of Equation of a Circle sounds like a pretty tough job. After all, there are only so many ways you can find the co-ordinates of the centre and the length of the radius, right? Well, perhaps not, as this lovely little resource shows.

Students are presented with a clock where, instead of numbers around the outside there are… wait for it… equations of circles. Students must use these equations to find the radius of the circle in order to determine if each of the numbers are in the correct place. Skills such as completing the square and algebraic manipulation will be crucial here. Furthermore, as an extension activity, students can be challenged to correct the wrong times.

Thank you for sharing!
