Sample Activity (.pdf)	Qualitative Grapher Highlight the meaning of a function, and see how it can be seen as something changing over time, with this tool that links a motion model to a graph.	User's Guide FAQ Warm-Up Sample Activity (.pdf)	Piecewise Linear Grapher Highlight the language of domain and range, and the ideas of continuity and discontinuity, with this tool that links symbolic and graphic representations of each interval of a piecewise linear function.
User's Guide FAQ Warm-Up Sample Activity (.pdf)	Linear Transformer Highlight the meaning of each component of a linear function's symbolic expression with this tool that links symbolic and graphic representations of translating (dragging) a line vertically or horizontally, rotating it around a fixed point, or reflecting it around the x- or y-axis.	User's Guide Warm-Up Sample Activity (.pdf)	Function Analyzer Highlight the rationale behind symbolic operations used to solve a linear equation with this tool that displays changes in the graphic and area models of functions as you change the value of each symbolic element.
User's Guide FAQ Warm-Up Sample Activity (.pdf)	Quadratic Transformer Highlight the meaning of each component of a quadratic function's symbolic expression with this tool that links symbolic and graphic representations of translating (dragging) a parabola vertically or horizontally, dilating it, or reflecting it around the x- or y-axis.	User's Guide FAQ Warm-Up Sample Activity (.pdf)	System Solver Highlight how symbolic operations on a system of linear equations do (or do not) change the graphic or tabular representations of the system. Note that the System Solver is a tool intended to illustrate the rationale behind the symbolic operations used to solve systems of linear equations, and not a way to learn what procedures to follow.
User's Guide Warm-Up Sample Activity (.pdf)	Plop It! Highlight how changing a data set affects the mean, median, and mode with this tool (created by The Shodor Education Foundation and modified by The Concord Consortium) that allows you to add and delete data graphically.	User's Guide Warm-Up Sample Activity(.pdf)	Proportioner Highlight proportion and scale with this tool that allows you to compare image dimensions by using one image to "paint" another.
