This document presents a basic numerical skills curriculum for use in either Academic Remedial Training or Apprentice Training in the Navy. The curriculum is designed to enable students who are deficient in numerical skills to attain at least minimal proficiency in elementary mathematics. The Training Analysis and Evaluation Group (TAEG) field-tested the curriculum with recruits awaiting entrance into the Fireman Apprentice Training course in Orlando, Florida. Results were seen as positive, with student performance measures indicating that a group with an initial mean mathematical grade level of 6.9 raised their proficiency to above grade 8 level after an average of eight days of instruction. This indicated that the curriculum successfully taught basic mathematical skills. This guide presents a complete description of skills taught, instructor activities, supplemental reading materials, and criterion tests. (The curriculum is referred to as the Mathematical Skills Curriculum, but this name has been changed to Numerical Skills Curriculum). (MP)
