As Kaitlin was not clear on subject -verb agreement rules when the operative verb is a form of the verb"to be" today, I first on the board conjugated the verb "to be" in past and present tense. Then, I distributed two subject-verb agreement exercises .I addressed how to locate the subject of the sentence -never in the prepositional phrase. We then completed subject -verb agreement exercises where the subject follows a form of the verb "to be." During the remainder of the class, we reviewed Kaitlin's PSAT practice test homework focusing on logic transition questions.
