So far, she hasn't said anything to the effect of "make sure you add another dollar per lesson." I add up all of my lessons and just give her an amount at the end of the month and she writes me a check.
I like the idea of speaking to her directly, and the wording used by Craftlady *Do I start my raise this month?*

If you are a hesitant to take that approach, you could always give her the amount at the end of the month with the option of two different figures, one designated as having the previously mentioned raise included.
