I would recommend preparing the lesson plan and the games for the whole month before the start of the lessons, and eventually adapt it to the students' needs.
I had classes four days a week, from 9am to 2pm. The day would start with the beginner level students and consisted of basic vocabulary and games. At 10:30am the intermediate students came to class, and we reviewed the most important grammar rules, verbs and pronouns, and writing. At 12:30pm I had advanced class and we discussed current topics and issues, and prepared some sketches.
My biggest fear was not to be able to give proper lessons, I had never been a teacher before and it was clear to me what obstacles I would be facing in the classroom.
In the end, it was much easier than I had expected, as my students really liked me and we built relationships based on mutual respect and entertainment.
I can assure you that this program is amazing, and it allows you to plunge into Moroccan culture. You're always in touch with local people, and my host family was really welcoming.
Moreover, the schedule allows you to travel on the weekends so you can relax while enjoying the beautiful landmarks of the country (for example, I went to Marrakech, Ourika, Martil, Chefchaouen, and Essaouira).
I loved Morocco so much that I went back to visit my host family twice in the past six months!
