Equipped with this handy reference of more than 400 illustrated definitions, children will be able to quickly find the definitions and illustrated examples that will enable them to solve many of the math challenges they face. Covering everything from "addend" to "zero," this comprehensive resource gives students definitions, illustrations, and examples that can help them solve math problems.

This handbook includes illustrated, concise explanations of the most common terms used in general math classes. The 400 illustrated definitions and examples are categorized by subjects that include:

• measurement,
• algebra,
• geometry,
• fractions and decimals,
• statistics and probability, and
• problem solving.

Each term has a concise definition and an example or illustration. This is a guide that needs to be in every child's desk.

The Math Dictionary is much more than a compilation of words and definitions. This book has been organized to reflect the different areas of mathematics taught in elementary and junior high schools. Within each category are all the terms commonly used in this field of study, concise definitions, and many examples and illustrations. In addition, the last chapter provides instructions for basic operations and tables of commonly-used facts and equivalents.

Editorial Reviews

This resource is much more than a compilation of mathematical terms. It lists terms and their definitions by such mathematical topics as measurement and geometry but also includes examples and illustrations. The illustrations are simple and clear and easy for most students to understand.

The terms in each category are comprehensive and will contribute to any student’s knowledge base in mathematics as well as complement most teachers’ lessons. The mathematical topics that the book covers most often are taught in the later elementary and middle school years. They include general topics such as numbers and operations, algebra, geometry, fractions, and problem solving. The end of the book includes numerous handy reference sections such as formulas, tables, charts, and an index.

When students encounter clear and concise illustrations and explanations of terms such as those in this book, they often retain the concept for a longer period of time. I strongly recommend that both students and mathematics teachers use this book. It can serve not only as a student reference, but also as a reference for teachers.

My students were impressed with the explanations of symbols and the ease of use. They also appreciated the fact that the book showed examples of processes rather than just giving definitions.

Math Dictionary for Kids may be used effectively in a variety of ways. It would definitely be an often sought reference book in any grade 4–9 math classroom, but it offers much more than simple definitions. The book’s clear style and inclusion of many strategies for success in problem solving make it well adapted for independent instruction. In fact, math educators looking to transcend the pedantic and repetitive pseudo-pedagogy that currently benumbs so many of our K–12 classrooms might find Math Dictionary for Kids to be a welcome resource for creative, content-based lesson enhancement. At the very least, it would be a welcome supplement to any math program. The book could be particularly valuable in multi-grade settings and/or classrooms with a wide range of student achievement levels or learning styles. That is, students who readily recall that a “transversal” constitutes “a straight line that intersects, or crosses, a set of lines,” and those who don’t, are likely, along with their teachers, to appreciate the style, content, and support of Theresa R. Fitzgerald's Math Dictionary for Kids.
