Grinity- you are so right, this is NOT the hill to die on! Mostly, I am trying to understand Accelerated Math so I can ask educated questions. I've learned a lot from our discussion and lots of googling. While I do not think this is an acceptable substitute for proper differentiation, she's at least trying something at this point.

We'll keep doing our thing and bide our time while she figures out the new program and whether or not it will actually help her.
