Algebra Visualization Tools
Dynamic graphs can help students understand the relationships
between the parameters in an equation and the shape and position of the
graph of the equaiton. These five tools let students change
parameters by sliding a controller along a scale and instantly seeing
the effect that has on the graph. To help focus students'
explorations they are challenged to try to match an existing graph by
changing the parameters under their control.
As you explore these tools ask yourself what effect each parameter has.
See if you can answer these questions:
- What controls the vertical
position of the graph?
- What controls the
horizontal position of the graph?
- What controls the orientation
of the graph?
- What controls how wide
or narrow the graph is?
- What determines the overall
shape of the graph?
Note: These tools require the Java Plug-in available from www.java.com/getjava/
