Today's lesson focused on grammar and punctuation. I reviewed the function of the comma, the colon, the semi-colon, and the dash. We further addressed how to recognize and to correct run -on sentences and sentence fragments. Kaitlin then answered PSAT practice questions on these topics. As we work through the questions, I continue to explain what makes the correct response the best choice and why the other punctuation choices are wrong, often because they create run-ons and sentence fragments. Kaitlin continues to do well on the practice exercises.
