Students will learn about sets of real numbers using different notations. Roster notation lists all elements of a set, while set builder notation describes the properties elements must satisfy using symbols like ∈ and ∉. Examples show using set builder notation to define the set of real numbers greater than -4 and integers between -2 and 14. A graphic organizer is provided to classify types of real numbers into sets defined with standard notations like R, N, Z, Q, and I.
