The target students, as with everyone else, struggled with subtraction. All of the target students were in the volunteer 'I don't get it' group on Tuesday. I take this as a win, because at least they are self-aware and recognised they didn't understand it, and by coming down for a second session, were able to demonstrate to me that they WANTED to learn it.
I have videoed a session with three of the target students (the others being away today, argh!).
These three do the most speaking in the video, as they are the target students. The other two students did answer and fully participate, I just edited out their parts as the focus was the target students.
(There are obviously chunks missing/edited out, or times when I show one example of a particular thing (e.g. addition on whiteboards) when in reality we did 5, just to make the video shorter).
Here is the observation run sheet (plan) for this lesson.
