Most students know pi is irrational, but some can't name any other irrational number, or explain why pi is irrational. The speaker will explore ways to describe irrational numbers. Then participants will work individually and in groups with geoboards, origami paper, and adding-machine tape to create models that make sense of irrational numbers.
