A 20 slide PowerPoint presentation that discusses the difference between fact and opinion, then gives students the chance to distinguish between the two using examples that are interesting and relevant to them. It's not pretty, but it's functional. A very fun way to introduce your non-fiction unit. I follow up this PowerPoint with the "Distinguishing Fact from Opinion" worksheet that is free on my page.
