Prompt You have been working through a lot of material that includes sorting grammatically correct and incorrect sentences. Directions: Take a look at the sentences below that require spelling changes in the preterite tense for (-CAR, -GAR, -ZAR verbs). Observe the situations when a spelling change is needed and what the change is. Make your best guess and create a general grammar rule for these 3 types of verbs, in your own words, that you think could explain the grammatical structure. Then, test your rule to see if it applies to the example sentences. We are not looking for a textbook grammar rule, but rather a creation of your own. Hint: Note the subject pronoun. Pay attention to the type of verb. (-ar, -er, -ir) Determine the conjugations for regular preterite tense verbs. See if any patterns occur.
