Foreword
Math Mammoth Grade 5-B Worktext covers the second half of fifth grade mathematics studies. In part 5-A, students have studied the four operations with whole numbers, large numbers, problem solving, decimal arithmetic, and statistical graphs. In this part, 5-B, we study more about decimals, a lot about fractions and fraction arithmetic, and geometry. Chapter 6 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 topic of focus for 5th grade, besides decimals. The most difficult topic of this chapter is adding and subtracting unlike fractions, which is done by first converting them to equivalent fractions with a common denominator. 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. From there, students will learn to draw circles, to classify triangles and quadrilaterals, and the concept of volume in the context of right rectangular prisms (boxes).
I wish you success with teaching math! Maria Miller, the author
