Math Mammoth Grade 5-B Worktext (International Version) is the student book for the second half of grade 5 mathematics, and part of the Math Mammoth Grade 5 complete curriculum. This book covers decimal multiplication and division, fraction addition and subtraction, fraction multiplication and division, and geometry.
This book starts with chapter 6, which continues our study of decimals. The focus is on multiplying decimals by decimals, dividing decimals by decimals, and conversions between measuring units. Chapter 7 covers the addition and subtraction of fractions - another focus topic of 5th grade besides decimals. In chapter 8, we study the multiplication and division of fractions from various angles. Chapter 9 takes us to geometry, starting with a review of angles and polygons. Then, students learn to classify triangles and quadrilaterals, and study the concept of volume in the context of right rectangular prisms (boxes).
Being a worktext, the book contains both the necessary instruction and the problems and exercises (the 'text' and the 'work'), and is for the most part self-teaching.
