Using the standards issued by the National Council of Teachers of Mathematics as a foundation, this book covers both content and process standards for areas such as algebra, geometry, measurement, problem solving, and reasoning/proofs. It also includes a glossary of math terms and dozens of suggestions for additional children's reading to further math understanding.
