In today's world, too many "arguments" come down to Right vs. Left, Facts vs. Opinions, and other examples of Us vs. Them.

Teach your students to present clear arguments (and avoid rhetoric and talking points) for their positions by using these worksheets.
Unless you're a parent, "Because I said so!" doesn't really make a compelling argument for someone to agree with you. Find real reasons with these worksheets.
