The goal for language teachers at my school is to read a minimum of 2 novels with the students per level. I prefer to read a novel in 12-15 days instead of drawing it out to a month or longer.
A good way to review the events of the previous chapter before beginning a new chapter is to make a collage using the PicCollage app. The app has images within the app that are copyright free, making it quick and easy for the teacher or students to create the collage in a short period of time.
This summer I'm going to shop around to check prices for making collages of El Nuevo Houdini into posters for the classroom. After reading a chapter, I can then hang the posters around the room. This will help students to remember the events of the previous chapters. If a student is absent the day we read a chapter, the other students will have a handy visual to refer to when they explain the events to their classmate(s).
Or..display the poster photo collage before reading the chapter to predict events. An variation of this is to create a collage with 1-2 photos not related to the chapter and ask students to guess which photo(s) are the imposters.
It also might be a nice way to have a verbal quiz at the end of the book.
Another bonus, hang the posters in the hall to help showcase what your students are learning in class. Better yet, record a student telling a review of the chapter, connect a QR code to the recording, and post the QR code along with the poster in the hall!
