Here's a grammar application program that helps prevent the five most common usage problems in the English language. Give your children a clear understanding of subject-verb agreement, personal pronoun functions, interrogative pronouns, comparatives and superlatives, and troublesome words (like good/well). Includes a student workbook with worksheets, tests, and quizzes; teacher's manual; and exercise cards. Note: This program is to be used any time after completing the Basic curriculum.
