Mathematical Explorations: Batty Functions: Exploring Quadratic Functions through Children's Literature
Keyword(s):
Many middle school students do not realize that functions and mathematical relations are present in their everyday lives. For example, the number of calories a student burns is a function of how long the student runs; the amount of pizza available to be eaten is a function of the diameter of the pizza. These examples of functions found in our daily lives can be described in a variety of ways, including with tables, graphs, and possibly symbolic generalizations. Many students do not realize that functions and relations exist outside of the mathematics classroom and that they can be represented in numerous ways (Billings and Lakatos 2003).
