Doing a planning about how to do a lesson is the most important step to follow in the moment to preparete a class, but it requieres some steps to follow that I cannot forget, also is important too to know about the subject, the topic, vocabulary and to get acquainted with the material etc..
I think the first the first three years of this subject we have studied the grammatical subject but how to put all these things in practical at the school? So me as a teacher have to follow an order, a structure about how the class is going to be, knowing the students needs, think about them, how many they are and who the students are. Considering many aspect such alearning styles, maturity, learning trategies. I realized that is very important o consider allthese thing to achieve the goald of teh lesson.
Also e siportant too, organize aim, time prodecure, resources these are very imporatnt things to considerate when we have to do a plan.
In conclusion from my experience, planning a class needs time and knowlegde about what I am doing and why, because I have to know what and how I am going to teach, but I think with practice then I will be able to do a plann in less time because the practice make the master.
