"Revision/ Refresher" Workshop

I attended the Primary 5 & 6 Mathematics and Science workshop at SCGS from 6-8pm. As usual, I went alone as the girls' father had no interest in knowing/ learning such things. Again, I saw the surprised looks on my ex-colleagues' faces upon seeing me lol. They always feel that I already know the things that they are going to present so I need not attend. I know things haven't changed much since I last attended the workshop in 2013 and since I last taught the subjects in terms of teaching approaches. But the workshop is good as a revision or refresher for me. :)
