This lesson has students infer the rules based on examples, which superior to learning the rule first and then getting examples, because the student creates the knowledge herself. This unit cover commas, periods, ellipses, and internal quotations. If the student click the wrong answer, he will be redirected back to the question to try again. Students enjoy it! I made it with Powerpoint and Mac Keynote which both allow you to use a "go to slide x" function. It does get complicated when you have a lot of slides, so I am making another one for verb and pronoun agreement and how to trim a quotations. It's pretty cool!
