This document provides a lesson on real numbers. It defines real numbers and their subsets, which include rational numbers like integers and fractions, and irrational numbers. Examples are then given to test understanding, such as identifying irrational numbers, numbers between 2 and 3, and ordering real numbers from least to greatest. Finally, it asks students to find the lengths of sides of squares given their areas.
