Math Mammoth Grade 6-A Worktext

nMath Mammoth Grade 6-A Worktext is the student book for the first half of grade 6 mathematics. This student worktext contains both the necessary instruction and the problems & exercises (the 'text' & and the 'work'; thus a worktext), and is fairly self-teaching. This is the 2022 edition. nThe main areas of study in Math Mammoth Grade 6-A are: nreview of the basic operations with whole numbersbeginning algebra topics: expressions, equations, and inequalitiesreview of all decimal arithmeticintroduction to ratios and percentprime factorization, GCF, and LCMa review of fraction arithmetic from 5th grade, plus a focus on division of fractionsthe concept of integers, coordinate grid, addition & subtraction of integersgeometry: review of quadrilaterals & drawing problems; area of triangles & polygons; volume of rectangular prisms with fractional edge lengths; surface areastatistics: concept of distribution, measures of center, measures of variation, boxplots, stem-and-leaf plots, histogramsThis book starts out 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 many different ways, and use properties of operations and the idea of maintaining the equality of both sides of an equation to solve simple one-step equations. We also study briefly inequalities and using two variables.

In chapter 3 we review all of decimal arithmetic, just using more decimal digits than in 5th grade. Students also practice conversions of measurement units.

Ratios (chapter 4) is a new topic for sixth grade. Students are already familiar with finding fractional parts of quantities from earlier grades, 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.

In chapter 5, the goal is to develop a basic understanding of percent, to see percentages as decimals, and to learn to calculate discounts.

Features nMath Mammoth focuses on conceptual understanding. It explains the WHY, so your children can understand the math, not just learn HOW to do it.

The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into
