Math Mammoth Grade 5-A worktext (Light Blue Series) is the first student worktext for fifth grade in the Math Mammoth curriculum. This is the 2023 edition. The first chapter covers operations with whole numbers (e.g. multi-digit multiplication and long division with two-digit divisors). We also study divisibility, factors, and prime factorization. In chapter 2, the focus is on large numbers and using a calculator. Then we study simple equations and problem solving, using a pan balance and bar models. Chapter 4 is about decimals and some operations with decimals. We focus on place value, addition & subtraction of decimals, and multiplication & division of decimals by whole numbers. Then, in chapter 5, students study the coordinate plane (first quadrant only), patterns in the coordinate grid, line graphs, and the concept of average. Features - Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the math, not just learn "HOW" to do it. - Concepts are often explained with visual models, followed by exercises using those models. These visual models can take the place of manipulatives for many children; however, it is very easy to add corresponding manipulatives to the lessons if so desired. - The curriculum is mastery-oriented. This means it concentrates fairly long on a topic, delving into its various aspects. This promotes conceptual understanding, as opposed to spiral curricula that often tend to jump from topic to topic too much. - Very little teacher preparation is required. :) - The curriculum has no separate teacher's manual nor is it scripted. The introduction to each chapter has some notes for the teacher concerning the material in the chapter. All the instruction is written directly to the student in the worktext, and there also exist accompanying videos where you can see Maria herself teach the material. - After each chapter introduction, you will find a list of Internet links and resources (games, quizzes, animations, etc.) that can be used for fun, illustrations, and further practice. Please note this book is spiral (coil) bound. The second half of 5th grade math is covered in Math Mammoth Grade 5-B worktext (available separately at Lulu). Also available for grade 5 are the answer key book and a book containing cumulative reviews and chapter tests.
