Math Mammoth Grade 3-B Worktext (Canadian version) is the student book for the second half of third grade math. In this part B, the main areas of study are:

place value (4-digit numbers) the concept of division and basic division facts; geometry (area and perimeter); measurement; fractions.

The curriculum is essentially the same as the U.S. version of Math Mammoth Grade 3, only customized for the Canadian audience in these aspects:

The curriculum teaches the metric measurement units. Imperial units, such as inches and pounds, are not used. The spelling conforms mostly to American English, taking into account a few key differences where Canadian English follows British English. Numbers are formatted with a space as a thousands separator, and a point as a decimal separator. Page (paper) size is Letter.

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, which is a big help to most parents. 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. For multiplication tables and division facts, you can use our online practice program (free).

A companion to this book, Math Mammoth Grade 3-A worktext, covers the first half of 3rd grade math (available separately).
