Math Mammoth Grade 5-A Worktext - Maria Miller

\nMath Mammoth Grade 5-A Worktext is the student book the first half of grade 5. 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 2023 edition. \nThe main areas of study in the grade 5-A worktext are: the four operations with whole numbersplace value with large numbers and the judicious use of calculatorproblem solving & simple equationsdecimal arithmeticgraphing and the coordinate grid \nThe year starts out with a study of whole numbers and their operations. Students get to review multi-digit multiplication and learn long division with two-digit divisors. We also review divisibility and factors from fourth grade, and study prime factorization. \nIn the second chapter, the focus is on large numbers and using a calculator. This is the first time a calculator is introduced in Math Mammoth complete curriculum-thus far, all calculations have been done mentally, or with paper and pencil. I want students to learn to be critical in their use of the calculator and use it with good judgment. Every exercise where calculator use is to be allowed is marked with a little calculator symbol. \nThe third chapter is about equations and problem solving. We study simple equations with the help of a balance and bar models. The main idea is to get students used to the idea of an equation and what it means to solve an equation. Students also do a fair amount of problem solving using the visual bar model. \nThe fourth chapter is about decimals and some of the operations with decimals (the rest will be studied in chapter 6). Fifth grade is the time when students learn all the basic operations with decimals. In this chapter, we focus on place value with decimals, addition and subtraction of decimals, and multiplication and division of decimals by whole numbers. Multiplying decimals by decimals and dividing decimals by decimals is covered in chapter 6. \nIn chapter 5, we study graphing in the coordinate grid, line graphs, and average. Today's world has become increasingly complex with lots of data presented in the media, so our children need a good grasp of statistical graphs to be able to make sense of all of that information. \nFeaturesMath 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
