Mathematics is much more than numbers, formulas, and theories. It is a vital, fascinating part of our daily lives. Whether we’re hitting a grand slam, making chocolate chip cookies, or reading a science-fiction novel, math helps us understand and enjoy the world in which we live.

The Tall-Tale Math Series is a comprehensive resource that empowers students by helping them understand and utilize the fundamentals of mathematics. Highly creative story problems spark curiosity and help students appreciate math as a powerful tool for solving real-life questions.

In Book 1 of the series, Number Sense, students will explore various forms of numbers, including integers, fractions, decimals, and percents. They will learn to compare different types of numbers and to use them in various kinds of computations.

Number Sense, is divided into three useful sections:

Review Sheets contain easy-to-understand definitions and examples that clearly explain particular concepts, such as “Adding Fractions.” In addition to providing valuable practice exercises, the sheets can also serve as handy reference guides.

Skill-Builder Sheets present intriguing story problems that use humor, creativity, and mystery to engage students. Each sheet covers a specific concept, which is clearly labeled at the top of the page.

Extra-Practice Sheets are designed to add an additional challenge for students who have mastered the previous sheets. In addition to the basic concepts, students must use additional skills, such as measurement conversion, chart analysis, and selection of the most appropriate number form. These sheets give teachers the extra flexibility to tailor lessons based on grade level and ability.

Learning Objectives
Number Sense was designed to help instructors implement the National Council of Teachers of Mathematics Curriculum and Evaluation Standards. Aimed at students in grades 4 through 8, the sheets will help students meet the following specific objectives:
      • understanding various ways to represent numbers, including fractions, decimals, and percents
      • comparing various types of numbers and understanding their relationships
      • representing, comparing, and ordering integers
      • computing with fractions, decimals, and percents
      • working with mixed numbers and improper fractions
      • utilizing factors and multiples to solve problems
      • rounding various types of numbers, including decimals and percents
      • finding appropriate forms for fractions, decimals, and percents in problem solving
      • connecting math to the world outside the classroom
      • using investigation and reasoning to solve problems
