Math Mammoth Grade 3-B Worktext (Canadian version) is the student worktext for the second half of grade 3, and part of the Math Mammoth Grade 3 complete curriculum. This curriculum is essentially the same as the U.S. version of Math Mammoth Grade 3, only customised for the Canadian audience in these aspects: - The curriculum teaches the metric measurement units. - Numbers are formatted with a space as a thousands separator, and a point as a decimal separator. - Page (paper) size is Letter. The "Grade 3" refers to the U.S. grade 3, and corresponds roughly to Canadian school system's year 4. This book, the 3-B worktext covers place value with 4-digit numbers, the concept of division and basic division facts, geometry (area and perimeter), measurement, and fractions. Please note this student worktext does not contain the answers. 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. - There is a strong emphasis on mental math and number sense. - It requires very little teacher preparation. - 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. - For multiplication tables and division facts, you can use our online practice program (free).
