Skills Review Workbook

This workbook is supplemental, and provides additional practice for the topics in the curriculum. I recommend you only purchase it once you are sure the student does need supplemental practice. Learn more.

At the heart of the curriculum are two student worktexts (A and B), each covering about half a year of maths work. These worktexts contain all the instruction and the exercises in the same book — which makes lesson preparation a breeze. The worktexts are written directly to the student, and thus they allow many children (if they can read) to teach themselves and to learn directly from the books.

You will also get separate answer keys, chapter tests, additional cumulative revisions (I do recommend you use at least some of them), and a versatile worksheet maker (Internet access required) for those times when your child needs just a bit more practice.

This curriculum is essentially the same as the US version of Math Mammoth Grade 7, only customised for the international audience in these aspects:

• The curriculum teaches the metric measurement units. Imperial units, such as inches and pounds, are not used.
• The spelling conforms to British international standards (British English).
• Page (paper) size is A4.
• Large numbers are formatted with a space as the thousands separator (such as 12 394). (The decimals are formatted with a decimal point, as is used in the US version.)

In money-related word problems, the symbol used is "$" (dollar).

The US version of the curriculum is aligned to the Common Core Standards, which means this curriculum may not be properly aligned to the seventh grade standards in your country. However, you can probably find material for any missing topics in neighbouring grades, which means you can simply re-order the material to solve most incompatibilities between different standards.

Features

• Math Mammoth focuses on conceptual understanding. It explains the "WHY", so your children can understand the maths, 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.
• 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.

Additional features for the download version

• The PDF files can be filled in on a computer, phone or tablet, using the annotation tools found in many PDF apps. Learn more.
• BONUS! The download version also comes with BONUS Soft-Pak programs. The 6 programs in Soft-Pak (4 math, 1 language arts, 1 list maker) offer both on-screen and printable activities in a low-graphic, high content format. Read more and see screenshots.

Overview of topics

We start out with an introduction to basic algebra, which is in many ways a revision of the same topics from 6th grade. The first chapter revises the order of operations, the concepts of an expression and equation and the distributive property. Students learn about the commutative and associative properties of addition and multiplication, and they simplify expressions that don’t involve negative numbers.

In chapter 2, we study integers and their operations in detail. Some of this is, again, revision from 6th grade, and some of it is new. The four operations of integers are explained with the help of two visual models: the number line and counters, hopefully providing an intuitive understanding of the processes. Students need to be able to add, subtract, multiply and divide integers when they learn to solve equations in chapter 3. In the end of the chapter students also learn about negative fractions.

In the next chapter (chapter 3) students study simple one-step equations. They already know the basics of how to solve these types of equations from 6th grade, but this time we use negative numbers in them.

Chapter 4 is titled Rational Numbers, which are simply fractions and certain decimals, so the student is already very familiar with them. The goal of the chapter is to be able to add, subtract, multiply and divide both positive and negative fractions and decimals and also do more complex calculations with them. We also solve simple equations involving fractions and decimals and learn about complex fractions.

The last chapter in part 7-A focuses on linear equations. The student learns to solve various types of linear equations and practises writing such for simple word problems. We also study linear inequalities, but not to the same depth as linear equations.

Part B starts out with a study of ratios and proportions (chapter 6). Students study unit rates, proportions, proportional relationships, scale drawings and floor plans.

The next chapter provides thorough lessons on the concept of percent. Students learn to solve a wide variety of problems involving percentages, including percentage of change and simple interest problems.

Geometry is our focus in chapter 8. Students draw geometric figures with given conditions (e.g. a triangle with 60° and 50° angles and a 6-cm side), and they also learn some basic geometric constructions. The other themes of this chapter are various angle relationships, area and the perimeter of a circle, conversions between units of area and of volume, surface area, volume and cross-sections when solids are sliced with a plane.

Chapter 9 is an introduction to probability. Besides learning the basic idea behind probability as the ratio of favorable events to all possible events, students compare experimental probabilities to theoretical ones in probability simulations and even design some on their own.

Lastly, in chapter 10, the curriculum covers statistical concepts. The major areas of study are random sampling and learning to compare two populations using some basic statistical measures and graphs.
