I had taught one year and did other jobs. Now I'm back on teaching. However, my students are getting really bored with the classes but I have to follow the methodology of a book strictly and that implies repetition and the same steps. I have tried to vary but they're still bored to the point of having problems with the order and discipline of the class. I teach two groups. One has 24 students between 7 and 15 years old and the other has 9 students between 19 and 30 years old. I'm desperate and don't know what to do. I would be most grateful if you could give some practical advice to solve this matter.
Thank you so much,
