I see your point, but I have to say that when I had prepared a lesson on a certain area of lexis/grammar/pronunciation or on a particular theme, I would keep the lesson plan afterwards. It was often useful, sometimes with very little amendment, for future lessons.
If you teach several fairly standard courses, the the overall lesson plans are often very similar for each group of learners. This is especially true if you are following a course book.
I have just saved lesson plans made up by other friends of mine that teach online, I have saved them over the years..... They are all different topics, grammer, conversation, leveled from 6-12. All PDF 45min - 1hr lessons...... Of course I would have to taylor or make up new ones if I didn't have one that fit for the students needs...
Thanks for the tip on the site... checking it out![]()
