When I learned them I started with the top E string found A then played and said it at the same time, so E string 5th fret. The A string is A so just play it and say it. D string 7th fret, play it say it. G string 2nd fret....ect

Then I did the same for the B string, C string... I didn't have a teacher then to tell me a better way. I choose it at the time because I liked the way it has me moving up and down the neck to find them, not just walking up strings.
