These activities are similar to the 'Révisons 4' set. The focus is language-based-grammaire, orthographe, vocabulaire etc.
There are twenty-one sheet, each one containing four sections.
I use them as homework, although you could certainly use them as bell work.
I assign each section separately, and take it up the following day. I project the sheet onto the white board and have a student lead the meeting. He/she asks members of the class to read the questions, come up and write the answers, and discuss the content. I take a back seat during these meetings, only intervening when necessary.
Many students tell me how frightened they were of speaking in front of their peers, and how comfortable they have become because of this type of activity.
Another great way to get your students to speak French!
