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.
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.
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.
Demonstrates the initial connections between functions and their graphs.
Two Variable Functions (Discussion)
Introduces 2 variable functions as ordered pairs and how to operate perform operations on ordered pairs.
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 Function Machine activity (http://www.shodor.org/interactivate/activities/FunctionMachine/).
This worksheet is for use with the Whole Number Cruncher activity (http://www.shodor.org/interactivate/activities/WholeNumberCruncher/).
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.
This worksheet is for use with the Data Flyer activity (http://www.shodor.org/interactivate/activities/DataFlyer/).
