Teaching Beginners Chords - Teaches that a major triad has more notes in between the 1st and 2nd note, and less between the 2nd and 3rd note (3 and 2 respectively). Then a minor triad is the opposite. Have Students try it on every note, all around the keyboard.
Teaching the Circle of Fifths - Have Circle of Fifths chart handy. Take 3 adjacent chords (like F-C-G) and show them how to play them. Put them to a rhythm to make music (quarter notes). Also try using their relative minors and write down possible chord progressions (beginning and ending on C at first)
Four-Chord Songs - Teach them the most commonly used progression and its Roman numerals (I-V-vi-IV)
Using Hook Theory - Show them the Hook Theory website and how to discover how other songs are written.
