Review by School Library Journal Review

Gr 5 Up-These how-to math books were designed to supplement instruction. Each one begins with a discussion of test-taking strategies. The layout is attractive; the effective use of white space will keep readers from becoming overwhelmed by the content. The titles are divided into brief chapters, each highlighting a basic skill or property, followed by problems in a "Test Time" box that's designed to look like notebook paper. The problems are "Multiple Choice" or ask readers to "Explain Your Answer" or "Show Your Work." "Test-Taking Hint" and "Definition" text boxes are prominent throughout the series; some of them are repeated in different volumes. Valuable resources for independent study, tutoring, and supplemental classroom material. (c) Copyright 2012. Library Journals LLC, a wholly owned subsidiary of Media Source, Inc.

Review by Horn Book Review

Each reference book provides explanations, definitions, examples with step-by-step solutions, samples of various question types with answers, and test-taking hints for twenty-four sequential mathematical procedures/operations. With only four pages and two test questions dedicated to each skill, the series is not intended for thorough practice and drill but offers a useful refresher. Multiple design elements make the content digestible, even for the math-phobic. Reading list, websites. Ind. [Review covers these Ace Your Math Test titles: Addition and Subtraction, Fractions and Decimals, Geometry, Multiplication and Division, Percents and Ratios[c1], and Pre-Algebra and Algebra.] (c) Copyright 2012.
