I would love to use the graphing feature of the assessment tool. But, it doesn't appear to be very useful to an algebra teacher as it is currently programmed.
A starter idea is to make interactive points that students could move to create a graph of a linear equation. There is so much potential here. Maybe it can be linked to desmos.com?
Also, can some Calculus symbols be added to the equation editor? Limits and integrals would be appreciated.
