203. Sunny Surd Sunflower

Today we have a guest contributor to the Sandpit – my colleague BH.

His Year 9 class have been studying Surds. They have just completed two particularly difficult Tarsia puzzles on simplifying surds. He celebrated their success by getting the class to create a ‘Sunny Surd Sunflower’ – what a great way to celebrate springtime and achievement.


UPDATE: Inspired by the bright sunflower, my class created an AVERAGE caterpillar!
