The purpose of this activity is to engage students in the lovely visual representation (Spiral of Theodorus) and see how it provides a natural progression of a series of surds.
- Spiral of Theodorus
About the Lesson
In this activity students use traditional pencil and paper techniques to construct the Spiral of Theodorus, after which they use the Geometry application on TI-Nspire to make the spiral dynamic. Students then explore consecutive hypotenuse, a series of surds, helping connect geometry and number.
