Circles is a program to aid independent learning in mathematics.

Circles was written for Mr Bakr Al Bazi, Mathematics teacher at the Grammar School at Leeds, who writes:

"3 circles, 6 values for each circle. Students started to investigate these values with no input from me."

"Independent Learning was taking place. Ratio, radius, diameter.... every notion that involved circles was discussed and then pi came in." 

"It was wonderful! I realised that adopting the use of new technology to support traditional instructions has not only it made me change the way I teach, but also the way students learn."
