This activity is intended to develop a concrete understanding of addition and multiplication of irrational and rational numbers, using the most ubiquitous of the irrational numbers: √2.
While this lesson is most closely connected to the Common Core Standard: Use Properties of Rational and Irrational Numbers, it also reinforces and builds upon (and for some students introduces) an often overlooked Common Core Standard: Solve real world and mathematical problems involving perimeters of pol
