Moved very slowly, Charlotte was sluggish and had to be forced to participate. She complained that she didn't have an "A" while every other teacher has given her one. She also sent a number of text messages while I was lecturing. She didn't do any of her homework problems and was barely attentive when I went over the answers. I finally got her to understand mole-to-mole conversions by the end, stayed on that topic till she got it as well as I could. Will pick up where we left off tomorrow morning.
