ABOUT THE SERIES: The books in the Math Clues Series provide a clear understanding of basic mathematical concepts. Each skill and concept is fully developed with lessons, practice, and motivating story problems. Each book in the series is divided into 3 sections: Introduction and Review of Concepts—The lessons present important mathematical concepts and teach students computational skills. Step-by-step directions and easy-to-understand definitions clearly explain each concept and procedure. This section will also serve as a useful reference for the lessons in the last 2 sections. Skill-Building Word Problems—Creative story problems use mystery and humor to hold students’ interest. Each lesson deals with a particular skill, and students are aware of the skill being practiced. Challenge Word Problems—These pages add an additional challenge for students who understand the concepts and have mastered the computational skills. Problems are similar to those in the second section; however, students are not told which skills are involved. Grades 3 to 5.

ABOUT NUMBER THEORY AND GRAPHING: Lessons focus on the following skills: even & odd numbers; factors & multiples; prime factorization; divisibility rules; data & samples; range, mean, median, & mode; interpreting & constructing bar graphs, line graphs, & pie graphs; line plots; frequency tables; stem-and-leaf plots; and histograms. 88 pages.
