I do not use any particular format to teach a lesson. My approach depends on the content of the lesson and how to explain them in a more detailed fashion. Of course, I go through the lesson before I sit to explain to my student. I also like to go into the depth of the topic and explore more. I also like to explore new ways to learn a lesson in whatever way I can. Also, I like to learn from my students at times when it sounds something new and interesting.
