Teachers have to come to the school an hour and a half BEFORE classes start to plan lessons. Otherwise the teacher would have nothing to teach!
Lesson planning time is not paid...it is just part of the job.
Schools have their own curriculum that you follow. The curriculum books will be provided by the school.
It is up to you to bring the lesson alive. This means using your own creativity and imagination. Often this means taking the content and applying it to your student's lives.
Teachers have to be efficient with their time since they have many classes to teach. This can mean only spending 20 minutes planning each class. Developing time management skills are important.
Lessons plans are the road map to a successful lesson.
