This worksheet is for use with the Possible or Not activity (http://www.shodor.org/interactivate/activities/PossibleOrNot/).
Introduces all of the 2 variable function and prisoner/escapee notions necessary to understand the Mandelbrot set.
Introduces and explains the concept of independent and dependent variables and their applications in real-world problems.
This worksheet is for use with the lesson Derivate (http://www.shodor.org/interactivate/lessons/Derivate/).
Inequalities (Discussion)
Introduces students to linear inequalities.
Derivate (Lesson)
Explores derivatives and the idea of infinity using a geometric interpretation of slope.
This worksheet is for use with the lesson InteGreat (http://www.shodor.org/interactivate/lessons/InteGreat/).
Multi-Step Functions (Discussion)
Discusses the notion of composite functions as several "number machines" with the output of one machine becoming the input of another.
This worksheet is for use with the Linear Function Machine activity (http://www.shodor.org/interactivate/activities/LinearFunctMachine/).
Parametric GraphIt (Activity)
This activity allows the user to plot ordered pairs and parametric equations on the same coordinate plane. The applet is similar to GraphIt, but instead allows users to explore the parametric representation of a function.
