This is a basic introduction or review of how to conjugate regular -ER and -IR Verbs in Spanish in the present tense. It works very well for Spanish 1 students who are already familiar with how to conjugate regular -AR verbs in present tense, or as a great review for Spanish 2 students as well.
The power point consists of 12 slides. It starts by quickly reviewing the correct order of the subject pronouns, then proceeds to discuss how to drop the -er / -ir and add the correct endings. There are example sentences using -er and -ir verbs as well. It also includes one slide that shows the slightly irregular conjugation of the verb "ver." The last slide of the power point shows a comparison between the ending of -AR, -ER, and -IR verbs, side by side so that students can see the similarities and differences.
