Math Mammoth Division 1 is a worktext that covers the concept of division, finding whole-number quotients within 0-100 (essentially, the basic division facts), and bar graphs and pictographs. It is most suitable for third grade, after the student knows the multiplication tables. The approach taken here to teach division facts is to simply base them on the multiplication tables, and not to teach them as a separate set of facts to memorize. This is very efficient and works well when the student knows the times tables. Several lessons in the book focus on this basic concept that division problems can be solved by thinking of multiplication. There are basically two ways to interpret division, and thus to illustrate it with concrete objects. The first way has to do with grouping. The problem 12 3 is interpreted as, "How many groups of three items can you make out of 12 items?" This is also called measurement division. The second way to interpret division is equal sharing: we divide or share items equally between people or other items. For example, the problem 12 3 can be interpreted as, "If you share 12 bananas equally between 3 people, how many bananas does each one get?" Both of these interpretations of division are important to understand so that the student can solve real-life and mathematical problems involving division. We also study division by zero. In that lesson, students should recognize that division by zero "does not work." The latter part of the book deals with bar graphs and pictographs. Earlier (in 2nd grade), students have drawn pictographs and bar graphs with single-unit scale. Now, they draw scaled pictographs and bar graphs from the given data, choosing the scale, or how many items one block in the bar graph or one picture in the pictograph signifies. This process provides practice in using both division and multiplication. This book will be relatively easy for students who have mastered the multiplication tables, since division facts are just multiplication tables "backwards". So, students can focus on another important skill: recognizing real-life situations in word problems that mathematically relate to either division or multiplication. This is very important to master so that the student can later on translate more complex situations into equations (modeling with mathematics).

Math Mammoth Grade 7-B Worktext is the student book for the latter half of 7th grade mathematics studies or the latter half of a pre-algebra course (Math Mammoth Grade 7 is a pre-algebra curriculum).The main areas of study in Math Mammoth Grade 7-B are: ratios, rates, proportions, and percentgeometry: angle relationships, compass & ruler constructions, drawing problems, pi and the area and circumference of a circle, cross-sections formed when cutting solids, surface area, and volumeprobabilitystatisticsFeaturesMath 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 very little teacher preparation 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.This is the full-color version of the worktext.
