This is longer than my usual videos, but it is so important. This is a look into what and how I do things in class, especially with the importance of regular revision at the start of 'every' lesson. Sometimes I do this at the end of a lesson - which is quite amazing that when the students might be 'brain dead' and lacking the ability to concentrate and I change what we are doing, all of a sudden they are all concentrating again - the power of variety!

There are 3 commonly used forms of writing a parabola. This video deals with all 3, but focusing on calculating the Turning Point from all 3 forms including some 'tricky cases'. This is good for the Australian Year 10A course and year 11 Methods or NSW Advanced Courses. Basically for those who are solid at their Math and looking for a career pathway that uses higher Math. It is presumed knowledge for much of further Math.

From my experience, the biggest secret is to watch each video 3 times across a week or more (which very few people do with anything, not just Math). I have tried to make this easier by keeping these videos quite brief.

After 40 years of enjoyable and rewarding teaching, I still love and continue to teach. It still amazes me how I continue to still think of better ways of teaching mathematical concepts and I also continue to discover methods of explaining things that help students 'better' understand and become more successful at remembering the concepts.

A word of warning from what I have repeatedly seen over the years - most of my videos are placed in a logical or reasonably sequential order and if you watch the first or second video in a playlist and feel comfortable with the concepts, please go to the last video in the playlist to check if you really are okay. Each video in a playlist usually becomes progressively more complex and the 'latter' or 'last' video will often contain common assessment questions where students are known to make errors.

I also often include some revision / consolidation / mixture videos in the playlist which I know are crucial to assist with student success in assessments.

I hope that you find this very helpful and a blessing in your studies.
