Review the properties of functions by looking at ten different curves and deciding whether or not they meet the criteria for a graph of a function. This activity simply displays the curves - it does not quiz the user.
Sample heart drawn on a coordinate grid for use with the Ordered Simple Plot Activity (http://www.shodor.org/interactivate/activities/OrderedSimplePlot/).
A more advanced version of Slope Slider, this activity allows the manipulation of the constants and coefficients in any function thereby encouraging the user to explore the effects on the graph of the function by changing those numbers.
