Excellent teaching of mathematics at the elementary school level requires teachers to be experts in school mathematics. This textbook helps prospective teachers achieve this expertise by presenting topics from the K-6 mathematics curriculum at a greater depth than is found in most classrooms. The knowledge that comes from this approach gives prospective teachers essential insight into how topics interrelate and where the difficulties may lie. Information is presented at a pace thatmakes it interesting, rewarding, and enjoyable. With the deeper mathematical preparation inherent in this book, prospective teachers will come away knowing how to explain concepts, demonstrate computational procedures, and lead students through problem-solving techniques. Both students and teacherswill find this book key to learning the necessary material and knowing how to express it at the right level. The primary focus is on the foundations of arithmetic, along with a selection of topics from geometry, and a wide range of applications. The number line is used throughout to visualize concepts and to tie them to solutions. The book emphasizes explanations: of concepts, of how to solve problems, and of how the concepts relate to the solutions of the problems. This is a textbook for acollege course in mathematics for prospective elementary school teachers. It will also be an excellent reference source for the instructors of such courses.Jensen, Gary R. is the author of 'Arithmetic for Teachers With Applications and Topics from Geometry' with ISBN 9780821834183 and ISBN 0821834185.
