Grammar, grammar, grammar! The Bookworm's Corner brings to you a worksheet to introduce and/or review two major topics of agreement: subject-verb agreement (SVA) and pronoun-antecedent agreement (PNA). An informational worksheet, it can be used during a writing review session in class, during a grammar lesson either in the whole class setting or in small groups, or even as practice at home following the "flipped-classroom" model. These concepts are important for emerging ELLs and average students alike, and even serve as review for the SAT and ACT. Also included is a very detailed teacher key, with explanations for answers and other suggested points of discussion.
