Seeing Math™ Secondary: Dynamic Interactive Software Makes Math Come to Life
Seeing Math™ has developed interactive software tools to clarify key mathematical ideas in middle and high school mathematics. Each interactive provides a real-time connection between representations of the mathematics (symbolic, graphical, etc.), so that changes in one representation instantly cause changes in the other. The interactives are accessible here or through our Seeing Math Secondary courses to:
- Illustrate
and reinforce key mathematical ideas for teachers and students
of algebra.
- Accelerate
learning and enhance comprehension of difficult concepts.
- Allow users to save images of the interactive and share them with other participants.

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.

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. |
