"Principles of Modern Elementary Mathematics (6 Grade)" is a sixth-grade level mathematics textbook, which examines and explores fundamental concepts of percentages, simple and compound interests, ratios and proportions, including polygons, polyhedrons, as well as circular and spherical bodies and other geometric concepts. It builds on the skills set attained in the 5th grade to extend the applications of basic arithmetic operations dealing with fraction, natural and fractional numbers. Theoretical treatment is synergized with practical considerations in the form of featured examples, exercises, problems with solutions and explanations to ensure that even the dullest pupil can acquire the deepest understanding, knowledge and the required skills set. The text is designed to promote and enhance the teaching and learning experiences for both teachers and pupils. "Principles of Modern Elementary Mathematics (6 Grade)" is intended and recommended not only for 6th grade pupils and their teachers, but also for an adult literacy program in which basic mathematics concepts and skills are taught. It is a contribution to the development and improvement of a community school curriculum on elementary mathematics.
J. Nyenetu Jarkloh is a Liberian-born graduate professional communications engineer, senior corporate manager and administrator, author and publisher, corporate communications specialist, policy analyst, and a staunch advocate for human rights. In Monrovia (Liberia), he attended the Amanda Caphart Elementary, Boatswain Junior High, Government Junior High, W. V. S. Tubman High, before enrolling at the University of Liberia (UL) in the College of Business. In the wake of Liberia's 1980 coup, based on excellent performance in his studies at the UL, he was granted a bilateral scholarship to pursue advanced studies in the former Soviet Union, where he earned a master's degree in radio engineering from the Odessa State Polytechnic University (Ukraine) Upon return to his native country, Mr. Jarkloh had worked as a senior instructor in the Electronics Engineering Department at the W. V. S. Tubman Technical College (now Tubman Technical University) in Harper (Maryland County, Liberia), a part-time lecturer in mathematics (Numerical Analysis) at the University of Liberia, and also as Manager of Planning, Research & Development Department of the Liberia Telecommunications Corporation (L.T.C.) (now Liberia Telecommunications Authority). He also holds post-graduate professional certificates in telecommunications planning and management from the Satellite Transmission Systems Inc (Long Island, N.Y.), INTELSAT, and the United States Telecommunications Training Institute (Washington, D. C., U.S.A). As a Fellow of the International Telecommunications Union (ITU), Mr. Jarkloh had actively participated in the ITU's GMDSS project, which called for elaboration of national master plans from English-speaking African Countries for the Development of Maritime Radiocommunications services. He elaborated his country's "National Master Plan for the Development of Maritime Radiocommunication Services in Liberia", which he defended during the final workshop of said project at the International Center for Theoretical Physics in Trieste (Italy). Due to the Liberian Civil Crisis, however, he was evacuated. He presently resides with his family in Ukraine.
