Demystifying Surds - an alternative approach!

Summary

Surds are traditionally a topic that students learn by rote rather than through a clear understanding. Unfortunately, how they are manipulated and their link to algebra is often missed. This workshop aims to reverse this paradigm by taking a quick look at the history of irrational numbers and their evolution. Participants will then use Pythagoras, number line activities and algebra to look at surds from a different perspective. Upon leaving you will have a great set of lessons to introduce surds with meaning.

Prior to coming, ask your students to draw a number line and mark where the square root of two and three lie respectively on this number line (do not give any hints or allow the use of a calculator) . Bring a sample of the the results with you for discussion.
