Design presentation slides that use key words and images to support a spoken talk, rather than full sentences meant to be read aloud.
The biggest slide mistake is writing full sentences and reading them straight off the screen -- the audience reads faster than the speaker talks, and the speaker turns into a reader instead of a presenter.
Strong slides use a few key words, a number or short phrase, and maybe one clear image, enough to remind the speaker and orient the audience, without replacing the spoken talk.

Common stumbles: Writing full sentences or paragraphs on a slide; cramming too many separate ideas onto one slide instead of spreading them across several.
