The author explains the test’s format in terms that younger students can understand, and then devotes a separate chapter to each pertinent math topic. They include: numbers, addition, subtraction, telling time, data and graphs, multiplication and division, measurement, geometry, fractions, and problem solving. Each chapter has problems to solve for practice and review. The book concludes with two full-length practice tests and an answer key.
