Japan loves structure, Throughout lessons are what makes teachers in schools happy. Sometimes they agree with your style and sometimes they don't. Sometimes a little persuasion will work, other times it won't. Just know, your efforts to help the students are what counts. I am a bit off the subject of structuring your lesson but note, helping the teacher of the school is more important than personal clashes of teachers.
Now back to structuring😅
When you structure your lesson decide who will play what role in the lesson.
As an example:
If the subject is phonics
Warm-up section: phonics
A) the reason - help them understand.
B) the students - what they will do (repeat, etc)
C) the teacher - what they will do ( help the students understand better, support, etc.
D) the ALT - perform, support, etc.
By doing this, you will give the school teachers a better understanding of your style and you can carefully think out your lesson plans.
