Graphing the Sine and Cosine Functions
Doing is more effective than watching. Learners use spaghetti to discover the relationship between the unit circle and the graph of the sine and cosine functions. As they measure lengths on the unit circle and transfer them to a...

Function-al Machines and Spaghetti Graphs
Sixth graders identify the relationship between patterns and functions. For this algebra lesson, 6th graders use a "Functional Machine" to identify the rule. Students use a function table to plot the points using play dough dots.

Stressed to the Breaking Point
High schoolers explore the relationship between the amount of weight that can be supported by a spaghetti bridge, the thickness of the bridge, and the length of the bridge to determine the algebraic equation that best represents that...

Graphing Polynomials
Students graph polynomial equations using different methods. In this algebra lesson, students identify the different ways the x and y values relate in a graph. They solve for x by finding the zero's of the polynomials.

Modeling Population Growth
Students investigate the reasons for taking a census and determine the problems that are involved in the process. They examine the population figure for Montana and Lake county before using the information to complete the included...
