This is the favorite vocabulary game of my French 1 students, and it is, by far, the easiest to play. I also play it with French 2.
The first page of the document is directions for the teacher, and the subsequent pages are templates for the game. This is a full class game, generally played with 3-4 groups, depending on class size.
Strengths of the game:
-students are speaking French
-it can take up as much or as little time as you want
-it can be used for any vocabulary set
