Two Variable Functions (Discussion)
Introduces 2 variable functions as ordered pairs and how to operate perform operations on ordered pairs.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
Sample figure drawn on a coordinate grid for use with Ordered Simple Plot Activity (http://www.shodor.org/interactivate/activities/OrderedSimplePlot/).
This worksheet is for use with the General Coordinates Game activity (http://www.shodor.org/interactivate/activities/GeneralCoordinates/).
Slope Slider (Activity)
Similar to other "flyers", Slope Slider uses slider bars to explore the effect of the multiplier and constant on a linear function of the form f(x)=mx+b. Explore the relationship between slope and intercept in the Cartesian coordinate system.
Introduces students to lines, rays, line segments, and planes.
This worksheet is for use with the Simple Maze Game activity (http://www.shodor.org/interactivate/activities/SimpleMazeGame/).
Polar Coordinates (Activity)
This activity allows the user to explore the polar coordinate system. The applet is similar to GraphIt, but instead allows users to explore the representation of a function in the polar coordinate system.
Caesar Cipher III (Activity)
Decode encrypted messages to determine the form for an affine cipher, and practice your reasoning and arithmetic skills. Input your guesses for the multiplier and constant. Caesar Cipher III is one of the Interactivate assessment explorers.
Introduces the notion of using modular arithmetic to encode messages.
