This Microsoft PowerPoint presentation contains 15 slides, and is a GREAT introduction to the French past tense (the passé composé).
It explains the following subjects:
1. the past tense in english
2. regular versus irregular verbs in french
3. the passé composé "equation" of conjugation
4. how to find a past participle/what it is
5. practice exercises for past participles
6. animated slide with 3 practice sentences in the passé composé
7. a short explanation of using negations in the passé composé
I use this presentation with my French II students as an introduction lesson on the passé composé. They follow the presentation's sequence of explanations very well, and I believe that it gives them a great foundation of the past tense. As you know, a good comprehension of this verb tense is imperative for higher-level French studies!
