Ten Additional Annotated Online Resources
This mathematical tool could be used in an Algebra 1 classroom one students have students functions; linear functions in particular. Students will continue to use what they understand about slope and y-intercepts while, at the same time, extending their knowledge to an understanding of restricted domain. Students can use this tool to model real-life situations and make the extension to piece-wise functions with pieces from other families.
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. |

Need a pentagonal pyramid that's six inches tall? Or a number line that goes from ‑18 to 32 by 5's? Or a set of pattern blocks where all shapes have one-inch sides? You can create all those things and more with the Dynamic Paper tool. Place the images you want, then export it as a PDF activity sheet for your students or as a JPEG image for use in other applications or on the web.

This resources uses a Flash interactive to investigate the shape of the curve y = a sin t and see what the concept of "amplitude" means. The sine curve occurs naturally when we are examining waves. The radius of the circle can change using a slider and affecting the graph.
