Elementary school classrooms are increasingly relying on a discovery method for the teaching of mathematics.Mathematics for Elementary Teachersthoroughly prepares preservice teachers to use this approach as it has been proven to increase their depth of understanding of mathematics. In this text, topics are organized by operation, rather than number type, and time is spent explaining why the math works, rather than just on the mechanics of how it works. Fully integrated activities are found in the book and in an accompanying Activities Manual. Students, as a result, engage, explore, discuss, and ultimately reach true understanding of the approachandof mathematics.
