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.
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.
Function Machine (Activity)
Students investigate very simple functions by trying to guess the algebraic form from inputs and outputs. Function Machine is one of the Interactivate assessment explorers.
This worksheet is for use with the Function Machine activity (http://www.shodor.org/interactivate/activities/FunctionMachine/).
Two Variable Functions (Discussion)
Introduces 2 variable functions as ordered pairs and how to operate perform operations on ordered pairs.
Demonstrates the initial connections between functions and their graphs.
Function Revolution (Activity)
This activity allows the user to find the volume and surface area of various functions as they are rotated around axes. This applet can be used to practice finding integrals using the disk and washer methods of calculating volume.
This worksheet is for use with the Graphit activity (http://www.shodor.org/interactivate/activities/Graphit/).
Graph Sketcher (Activity)
Students can create graphs of functions entered as algebraic expressions -- similar to a graphing calculator.
This worksheet is for use with the Whole Number Cruncher activity (http://www.shodor.org/interactivate/activities/WholeNumberCruncher/).
