Sorry this is a late update! It was a busy day today!
The lesson went much better! She wasn't resistant, either, which makes such a difference. It was downright pleasant! At first she tried to count first the tally sticks, and then the beads on the abacus, but after I reminded her that she's supposed to picture the amounts in her head, she did it with no problem. It was great to see her be able to do that!
I really wish I had written this post this morning right after the lesson. Now I can't remember much of what I wanted to write! :) I guess bottom line is that it went much better than the last two days!
