1. Topic: Stem-changing verbs
Essential question: How do I conjugate these new verbs and use them?

2. Verb conjugating – what do we already know?
You conjugate a verb when you mention who does it.
Every sentence needs a conjugated verb
There are two parts to each verb – the stem and the ending
There are –ar, -er and –ir verbs
The infinitive is the unchanged form of the verb
There are some irregulars

To conjugate, you take off the original ending and add the conjugation ending
For –ar verbs: -o, -as, -a, -amos, -an
For –er verbs: -o, -es, -e, -emos, -en
For –ir verbs: -o, -es, -e, -imos, -en
