This book contains a great deal of wonderful information in addition to the musical exercises, melodies, and etudes. His "Hints on Practical Study" is a great resource for any musician. This is a perfect starter for getting your younger students to become comfortable with sight reading and prepared materials in a variety of time signatures and key signatures.
