This power point presentation introduces students to stem changing verbs by comparing them to regular -AR, -ER, and -IR verbs. It is color coded so that students can see the stems and the endings easily.
The first 16 slides are the presentational notes while the last 16 are for student use. Just switch the background color and print off, and the students will have guided notes so they can follow along with the presentation. (I usually have my students color code their notes, too.)
Verbs included are:
* tener (yo-go)
* decir (yo-go)
