master of none, that's interesting about Mathpad! The tutorial for Mathpad Plus that I saw made it look like it would work well for this, but we're a Mac family so we didn't bother with trying it because, as you noted, it wasn't supported for the latest version of the Mac and they had no plans to upgrade it (this was several years ago). I had a feeling it might be headed in the direction of no longer being supported.

Irena, our ds started using Efofex when he was in Pre-Algebra (which is the course taken the year before Algebra in our school district). Our ds never used the equation module much, but he used the graph package a lot.
