I will teach the subject with logics beyond it, it is just to make sure the student understands the subject from depth and never forget. i have taught my kids the same way. i will adjust the teaching method based on the student capacity of understanding which is very important to make student feel comfortable and understand the subject slowly.i will also teach the tricks for easy calculations where they do not need calculators to solve simple problems. and these will be useful in students life and also helpful in developing self confidence and also it helps to perform better in other subjects as well.
