As part of AP's Unit 7, we today studied the use of punctuation both grammatically and to impart meaning. I provided instruction on proper usage of the comma, the dash, the semicolon, the colon, and quotation marks. Next, I addressed how punctuation can be used to add meaning, emphasis or pauses to slow down the reader . We then reviewed Matthew's AP homework exercises on this topic and addressed areas where he encountered difficulties ,such as the proper use of subordinate conjunctions to explain contrasting ideas.
