Students investigate linear functions by trying to guess the slope and intercept from inputs and outputs. Linear Function Machine is one of the Interactivate assessment explorers.
This worksheet is for use with the Whole Number Cruncher activity (http://www.shodor.org/interactivate/activities/WholeNumberCruncher/).
This worksheet is for use with the lesson Conic Flyer (http://www.shodor.org/interactivate/lessons/ConicFlyer/).
Investigate the first quadrant of the Cartesian coordinate system through identifying the coordinates of randomly generated points, or requesting that a particular point be plotted. Simple Coordinates Game is one of the Interactivate assessment explorers.
Introduces students to arithmetic and geometric sequences. Students explore further through producing sequences by varying the starting number, multiplier, and add-on.
This worksheet is for use with the Sequencer activity (http://www.shodor.org/interactivate/activities/Sequencer/).
This worksheet is for use with the Derivate activity (http://www.shodor.org/interactivate/activities/Derivate/).
Caesar Cipher II (Activity)
Encode and decode messages to determine the form for an affine cipher. Input a message to encode, then input your guesses for the constant and multiplier. Caesar Cipher II is one of the Interactivate assessment explorers.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
Cross Section Flyer (Activity)
Explore cross sections of different geometric solids: cone, double cone, cylinder, pyramid, and prism. Manipulate the cross section with slider bars, and see how the graphical representation changes.
