Update: I took DD to school Thursday morning, and spoke to the asst. principal about borrowing a home copy of science and social studies books. DD brought them home Friday afternoon. We spent about two hours last night catching up in the two subjects. She's caught up in social studies now, and just needs another hour or so in science. So that's basically three weeks and two subjects in three hours. That time even included a science experiment.

DD seemed to really enjoy it. My belief that she can get far more out of me on the subjects was augmented when I was able to relate just about everything the science book said about methods to the episode of Mythbusters we'd seen together the night before. That's not a connection a school teacher can be expected to make.
