Give input to the Whole Number Cruncher and try to guess what it did from the output it generates. This activity only generates multiplication and addition functions to avoid outputting any negative numbers. Whole Number Cruncher is one of the Interactivate assessment explorers.
Number Cruncher (Activity)
Similar to the original "Function Machine" but lists input and output in a table and will not let the user attempt to guess the rule without having at least two data points. Number Cruncher is one of the Interactivate assessment explorers.
Graphit (Activity)
Create graphs of functions and sets of ordered pairs on the same coordinate plane. This is like a graphing calculator with advanced viewing options.
Introduces students to the vertical line test for graphs of functions.
Teaches distinguishing between possible and impossible graphs of functions as well as causes of graphical impossibility.
Introduces the basic ideas needed for understanding functions.
Demonstrates the connections between formulas and graphs.
This worksheet is for use with the Function Machine activity (http://www.shodor.org/interactivate/activities/FunctionMachine/).
This worksheet is for use with the Two Variable Function Pump activity (http://www.shodor.org/interactivate/activities/TwoVariableFunction/).
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.
