Description: A guide to major, supporting, and additional clusters in Grade 5. At least 65% and up to approximately 85% of class time, with Grades K-2 nearer the upper end of that range, should be devoted to the major work of the grade. Note, the critical areas are a survey of what will be taught at each grade level. An important subset of the major work in grades K-8 is the progression that leads toward middle school algebra.*Teacher Advisor is 100% free.
