Bearings
Finally finished the first chapter of the year with the class. Started on Applications of Trigonometry - Bearings. Was very anxious and considering that I am behind schedule, went straight into the topic: how to identfiy the angle and find the value of the angle. Realised that towards the end of the lesson, most of them could identify the angle to find based on the question but had difficulty finding its value becuase they had forgotten about properties of interior angles, corresponding angles, angles at the centre, etc. So on Fri decided to take a step back and revised properties of the above mentioned angles and gave them a worksheet on it. Gratifying to hear some of them say that the questions were very easy but a handful of them were struggling with it. Got the ones who finished early to peer teach their classmates. Those who became my assistants felt very good about themselves. Going back to 'bearings ' again tomorrow.

Sometimes, we as teachers are so eager to be on schedule that we forgot to check the prior knowledge of our pupils and try linking their prior knowledge to what they are going to learn next. For NA kids especially, we have to constantly help them to recall at the beginning of the lessons due to their short retention of memory. With the repetition and recalling, they will eventually internalise some basic concepts.
