Written for the fifth- and sixth-grade levels, this workbook gives students practice in using context clues and reading comprehension to apply punctuation rules, as well as in carefully reading and following directions. Noting that the activities are based on the idea that punctuation is necessary to make written communication clear, the introduction states that with these activities, students must use context clues for analyzing, comparing, contrasting, and deducing. After the introduction, the activities are: Comma Series: What's What; Comma Series: Action; Comma: Who's Being Addressed (Nouns of Address); Comma: Separate State (City and State); Comma: Addresses (Street, City, and State); Comma: Around the Year (Month, Day, Year); Comma: Special Beginnings (Introductory Words); Comma: Who Says What (Dialogue); Conjunctions: Tie It Up; Comma: Explain It (Nonessential Appositives); Question Mark/Period: Questionable Endings; Exclamation Mark: Exclaimed or Not; Apostrophe: Leaving Out Letters (Contractions); Apostrophe: Who's an Owner; and Quotation Marks: Quote or Title? Includes 16 Sample Lessons and an answer key. (PM)
