It is easy reading and contains many practical, no nonsense methods for classroom management that actually work. No theory here; just real life examples that can easily be applied in the classroom. Many of the chapters give effective ways to encourage the unmotivated child. (I'm sure that each year you have one or two sitting in your class.) It is a book worth purchasing, reading, and sharing. AND many of the suggestions carry over into managing your own children.
The paperback book can be purchased on Amazon.com for about $10.00. Mackenzie has written several books, one entitled: Setting Limits with Your Strong-Willed Child: Eliminating Conflict by Establishing Clear, Firm, and Respectful Boundaries. I haven't read this one, but I wish it had been available when I was raising my first son!
