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

3. Verb conjugating – what do we already know?
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
