This is a partner game where each partner gets their own sheet, and they will need two dice per pair.
One person goes at a time. One die is rolled to find out what their subject pronoun is, then the same person rolls the second die to figure out what their -ar verb and sentence is. After they roll to get the subject pronoun and the verb, they will have to create a complete sentence correctly conjugating their verb to match the subject pronoun they rolled.
This game is a good way to get the students conjugating regular -ar verbs in the present tense, and is a good way for the teacher to assess who understands the concept of conjugation.
