Three TI-Nspire documents provide activities for students to carry out individually with handhelds or for teachers to use as in a whole-class setting using Navigator Teacher Software.

The Teacher Notes introduce the Crop Circle phenomenon and suggests a way of using the three activities:

  • Starter: Compass Rose;
  • Main Activity: Fractal Area;
  • Extension: The House of Pi.

The .tns files include instructions and questions for students and there is also a 2-page student handout.

This activity forms part of the OxBox, published by Oxford University Press in March 2010 to support their course 'Oxford GCSE Maths'. http://www.oup.com/oxed/secondary/2010gcse/
