To assist teachers in using the various Lee Evans materials, Dr. Evans and Hal Leonard Publishing Corporation asked Dr. Martha Baker to prepare teachers' manuals for the core books in the series. Dr. Baker is an expert in piano pedagogy and is Professor of Keyboard Studies at California State University, Fullerton. Take Ten For Jazz includes 33 ten-minute lesson plans so that each week, in the course of the regular lesson, teachers can take 'ten' for the study of jazz. Take Ten More For Jazz continues this same approach for four additional books.
