The Key to the Red Workbook gives clear, thoroughly-explained answers to all exercises in the Red Workbook, the second of four non-sequential books in the Grammar for the Well-Trained Mind series, providing detailed, well-designed exercises in the correct use of English grammar. The Key, along with the accompanying Red Workbook and the Core Instructor Text, make up Grammar for the Well-Trained Mind: a complete course that takes students from basic definitions (“A noun is the name of a person, place, thing, or idea”) through advanced sentence structure and analysis—all the grammar skills needed to write and speak with eloquence and confidence. This innovative program combines the three essential elements of language learning: understanding and memorizing rules (prescriptive teaching), repeated exposure to examples of how those rules are used (descriptive instruction), and practice using those rules in exercises and in writing (practical experience). Each year, parents and teachers go through the dialogue, rules, and examples in the Core Instructor Text; students follow along in the Workbook. This repetition solidifies the concepts, definitions, and examples in the student’s mind.
