The activity enclosed has an easy version (geared toward French 1) and a hard version (geared toward late French 2 and above).
The first part of the activity is a whiteboard activity (you could just have them write on slips of paper as well). There are twenty slides asking for the conjugation of different subjects with one of the four main verbs (etre, avoir, aller, faire). The easy version is JUST present tense. The hard version includes present, imparfait, passe compose, futur simple and conditionnel. Every conjugation they get right, they get a point.
The second part of the activity is an anagram activity. However many they got right in the first activity determines how many letters they get (which they fill in at the top). Then, they must make as many possible conjugations as they can using the letters. I had it as an extra credit activity, but feel free to change the wording to make it an assignment or even a game. When they make the conjugations, they also must indicate the subject and the verb of the conjugation (and the tense in the more difficult one).
