If your students are anything like mine, you may sometimes throw up your hands at the lack (or misuse) of commas in their essays and stories. I created the Comma Basics Series of Power Point lessons with the goal of identifying the most egregious types of commas errors and addressing them in a clear and engaging way.
Comma Basics III guides students in the use of commas to set off both "interrupter" words or phrases and appositives that add extra information to a sentence. The lesson employs active student engagement strategies and written practice throughout. I hope you find it helpful! - Rae Galeazzi
