I like tonight's lesson on average. The use of the newspaper report on how SBS and SMRT have overcharged transport fares is an eye-opener. Just from one article, the learning of average of can be applied. On top of that, other Math concepts can be applied in finding if the average amount of overcharged fare is 4 cents.
What I have learnt is that the teacher needs to be clear of what Math concepts or Math learning outcomes that he wants his student to learn. In my opinion, facilitating a Math lesson is challenging because a teacher needs to have the discipline and experience on how to facilitate the lesson. On the other hand, a teacher needs to start somewhere and then the experience gained will increase over a period of time.
