Copy into notebook.

2. Usually come before and, but, or
3. Are used when phrases introduce the sentence.

1. Are used to separate independent clauses (parts of a sentence that could be sentences on their own).
First determine if each sentence below needs commas or semicolons; some don't need any, some need several.  For each one, write the word that comes before the comma or semicolon you are inserting, the comma or semicolon, and then the word that comes after the comma or semicolon. The easiest way to see where they go is to read the sentence aloud to yourself. Remember, some sentences might be OK as is.
