This book is a classic and a must-read for every elementary teacher, curriculum consultants, reading and math specialists, directors, principals, and administrators. The best part is it is organized really well, EASY to read, with bullet points and side titles, in order to best grasp quickly in the moment, and to refer back to later. The table of contents and chapters are organized by broader guidelines, then one chapter for each age group from 4 years, 5 years, etc., up to 14 years. It's comprehensive and to the point, so when planning curriculum or preparing for a meeting, you go to only the section or sections you need to visit. BRAVO Chip Wood.
