French reading game: Le lutin sous l'arbre de Noël

I use this game when we start learning holiday vocabulary. My kids LOVE this game! They know "bug in a rug" from English class, so they are always really excited to play this version in French class with me. (Here is the same game in English). 

We choose 6-10 of the vocabulary trees, and one student gets to hide the elf under the tree of their choice. The students then try to guess which tree the elf is hiding under. They have to say the word in french (or use it in a sentence, if you have students who are ready for the extra challenge). Whoever finds the elf is the next one who gets to hide him.
