Creating a Polynomial Function to Fit a Table
Discover relationships between linear and nonlinear functions. Initially, a set of data seems linear, but upon further exploration, pupils realize the data can model an infinite number of functions. Scholars use multiple representations...

Parts of a Computer
Students, after identifying the parts of a computer, and categorizing the parts by functions (input, output, process, and storage), explore how all the parts of a computer work together. They compare/contrast the differences between...

How are we Related?
Students differentiate functions based on their domain and range. In this algebra lesson, students define function, domain, range and relation. They analyze graphs and coordinate pairs for input and output values making up a function.

Body Length Experiment
Students measure the lengths of their bodies and various body parts to determine the relationship (or lack of one) between body part length and the length of the entire body. A spreadsheet program is suggested for data collection.
