When I first started teaching, I remember feeling like the 2 hours of main lesson was an eternity. I thought it would be impossible to fill that time with valuable content.

These days I’m far more likely to run out of time and not get to everything than to have extra time on my hands. The truth is that when you understand the different components of main lesson, you’ll see how the time just flies by and you don’t need to figure out how to fill that 2-hour main lesson from scratch every single day.
