This PowerPoint has 33 slides and can be used to teach agreement of irregular French adjectives or to practice/review. There is a chart of common irregular adjective endings and then 30 slides; each slide has an emoticon and a very short sentence using the adjective in a sentence.
When I use this in class, I show the slide and have students make a sentence with a logical adjective. With a mouse click, it shows a sentence. Another mouse click brings up another/other forms of the adjective. Let me know if you have questions. Profette
