Great explanation given the text restrictions, - stepping away from the white notes, 7th chords are 135b7...as opposed to M7. My favorite way to confound beginners - 1 3 5 - five (fifth) 1 3 - three (third) 3 5 - three (third) Therefore 3 + 3 = 5. Once they get that, the rest is easy, especially explaining b13 notes etc.
