Math Mammoth Grade 6-A Worktext: 2022 edition (b&w)

Math Mammoth Grade 6-A Worktext (2022 edition) is the first student book in the Math Mammoth Grade 6 Curriculum, and covers the first half of sixth grade mathematics. Note: This is the black-and-white version and has grayscale interior pages. Full-color version is available separately.In this book, students encounter the beginnings of algebra, learning about algebraic expressions, one-variable equations and inequalities, integers, and ratios. We also review and deepen the students' understanding of decimals, and study ratios and percent as new topics for 6th grade.Being a "worktext" means the book contains both the instruction (the "text") and the exercises (the "work"), all written directly to the student. This makes the book self-teaching or nearly so for many students.The book starts out, in Chapter 1, with a review of the four operations with whole numbers (including long division), place value, and rounding. Students are also introduced to exponents and do some problem solving.Chapter 2 starts the study of algebra topics, delving first into expressions and equations. Students practice writing expressions in different ways, and use properties of operations and the idea of maintaining the equality of both sides of an equation to solve simple equations. We also briefly study inequalities and using two variables.Chapter 3 has to do with decimals. This is a long chapter, as we revise all of decimal arithmetic, just using more decimal digits than in 5th grade Students also convert measuring units in this chapter.Ratios (chapter 4) is a new topic. Students are already familiar with finding fractional parts, and now it is time to advance that knowledge into the study of ratios, which arise naturally from dividing a quantity into many equal parts. We study such topics as rates, unit rates, equivalent ratios, and problem solving using bar models.Percent (chapter 5) is an important topic because of its many applications in real life. The goal of this chapter is to develop a basic understanding of percent, to see percentages as decimals, and to learn to calculate discounts.The rest of the 6th grade topics are found in Math Mammoth Grade 6-B Worktext; which covers the second half of 6th grade math and is available separately. Also available separately is the answer key book, and a book containing cumulative reviews and chapter tests. Read more
