Fill in the blank with the Spanish word that best completes the following sentence.En la clase del __________________grado está la maestra que me gusta.

Spanish uses the shortened form tercer before a masculine singular noun when giving an ordinal number. Since grado is masculine and singular, the sentence is En la clase del tercer grado está la maestra que me gusta. Tercer means “third”; tres means “three” and does not express an ordinal here.
