Written for the third- and fourth-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 in the book are: Comma Series: Who's Who; Comma Series: What's What; Comma Series: Action; Comma: Who's Being Addressed; Comma: Separate State; Comma: Around the Year; Comma: Special Beginnings; Comma: Who Says What; Conjunctions: Tie It Up; Question Mark/Period: Questionable Endings; Exclamation Mark: Exclaimed or Not; Apostrophe: Leaving Out Letters; Apostrophe: Who's an Owner; and Quotation Marks: Quote or Title? Each exercise includes a rule and instructions and can be used for independent practice. Includes 12 sample lessons and an answer key. (PM)
