Product description Mathematics for Elementary School Teachers, 2/e, provides a unique opportunity for students to develop a clear understanding of mathematical concepts, procedures, and processes, to communicate these ideas to others, and to apply them to the real world.The goal is to achieve the optimum balance between presenting a thorough development of mathematical content and presenting it in a way that is understandable by students. The material has been revised so that it powerfully embodies the new Principles and Standards for School Mathematics of the National Council of Teachers of Mathematics. About the Author Phares O'Daffer was born and raised in Weldon, Illinois. He received his B.S.(1955) and M.S.(1956) from Illinois State University, studied at the University of Iowa(1958) and the University of Michigan(1962), and received his PhD in Mathematics Education from the University of Illinois(1968).

He was a high school mathematics teacher in Maryland from 1971 to 1974 during which time he simultaneously attended the University of Maryland. He received his master's degree from the University of Maryland in 1974. He attended Indiana University from 1974 to 1977 where he worked on a federally-funded research and curriculum development project on problem solving. He was a K-12 mathematics supervisor in a school district of about 30,000 students in West Virginia from 1977 to 1982 and then moved on to Illinois State University. He was a Professor in the Department of Mathematics and Computer Science at San Jose State University, California, from 1987 until January 2001 when he decided to pursue writing full time. Randy started writing textbooks for elementary and secondary school mathematics in 1978. He has written more than 75 textbooks for children and teachers. He has been involved in numerous activities with NCTM and has authored several NCTM publications, mostly in the area of problem solving. Randy has been a speaker at hundreds of state, national, and international mathematics education conferences and was a national speaker for the Learning magazine for many years. He is past vice-president of the National Council of Supervisors of Mathematics. Tom Cooney was born and raised in Toledo, Ohio. He received his B.Ed. and M.Ed. Degrees from the University of Toledo with majors in mathematics and mathematics education respectively and his Ph.D. in Mathematics Education from the University of Illinois in 1969. He taught middle and secondary school mathematics in Rossford, Ohio from 1960-1966 while completing his doctorate. Upon completion of his Ph.D., he went to the University of Georgia's Department of Mathematics Education where, aft
