Simplified Chords in Musical Notation

I think that the title of that lesson is just hilarious. It's the name of the lesson I'm using from the Standard Guitar Method by Dick Bennett in my classes. It sounds very cerebral. I guess it really gives away the book's 1965 copyright. I'm not a big fan of the method but I do like the way Dick breaks down the simplified three string chords.

He notates little chord-building exercises in standard notation. For example, on C and G7 chords:

E E E E - - - - - - - - E E E

- - - - C C C C - - - - C C C

- - - - - - - - G G G G G G G

These have been pretty effective even with my really struggling 6th graders. It's at least an easier way to teach a whole class chords without walking around and manually moving 6 or 7 students' fingers.
