This curriculum guide provides aid in organizing and planning for the mathematical needs of the individual classroom. It is recommended that: (1) each teacher study the entire curriculum to become familiar with the concepts that interlock and blend all the grades together, and (2) all students with average ability master 70% of the skills. The guide notes the educational philosophy of Portales, New Mexico; Mathematics Department objectives; departmental policies and procedures; and methods available for pupil evaluation. The scope and sequence of the mathematics curriculum in Portales High School is noted, followed by a brief outline of the basic skills to be mastered in kindergarten through grade six. The bulk of the document notes educational objectives for specific concepts at each grade level and course throughout the program, and provides guidance on expected learner outcomes, suggested materials and/or methods, and means of student evaluation.
