In response to a recent query from a friend of mine who is interested in becoming a piano teacher, I compiled this quick "to do" list of elements that have proven valuable in my own piano teaching adventures.
1. Purchase some beginning method books and become familiar with them. My favorite "teacher friendly" beginner level piano books are Piano Adventures by Nancy & Randall Faber. The wealth of online support ideas make this a great book to start with for teachers who are just starting out, and their songs are appealing to students as well. I have my students purchase the Lesson and Technique books. I teach them theory with online activities and games during lesson and lab time and supplement with other books from my music library instead of using the Performance book.
Another favorite method of mine is the Hal Leonard Series. The accompaniment CD's are especially motivating and engaging for the beginning levels and provide a fun support system for home practice to spice up the "simple sounding songs" at the start of music lessons. The presentation of concepts in both of these methods follows a similar order so I often interchange them to suit the tastes and needs of my students.
