The document discusses introducing the concept of rate of change in mathematics. It defines rate of change as a ratio that compares the amount of change in a dependent variable to the amount of change in an independent variable. Examples are provided to demonstrate identifying rates of change from sets of data where the rates may vary or remain constant. The document encourages completing any questions or examples to understand the definition and application of rates of change.
