Tips for slides students actually read

• One idea per slide. If you need two sentences of explanation, you need two slides.
• Big text, few words. Students in the back row should read every word.
• Show, then name. The diagram first, the term second.
• Make it in their language. DeckLume writes decks in the language you ask for, including right-to-left scripts.
