Series is designed to develop effective estimation skills for students in grades 6 to 8. Each book consists of 15 lessons that progress systematically through estimation strategies in addition, subtraction, multiplication, and division. When this foundation has been built, the lessons continue with estimating fractions, mixed numbers, decimals, and percents.
