This is a lesson I have created for the textbook Dynamo 2 (vert), Module 4 (Le monde est petit), unité 2 (Qu'est-ce que tu dois faire a la maison?).  
 
In this lesson students learn about:
How you must help at home
Using devoir + infinitive
 
The lesson includes three starter tasks and a variety of activities (genuine reading, translation, etc). This is a lesson for a mixed-low ability class, so I have not included too much information to keep things easy. There is a vocab sheet included. This lesson can also be used as cover.
