Grade 8 Mathematics

4 Seasons

Mathematical concepts and techniques are used in various contexts to solve problems. The mental processes involved in mathematics play a key role in enhancing accuracy, critical and logical thinking skills, as well as problem solving abilities. Having these skills is not only beneficial for mathematics, but this training of the brain contributes to decision making and problem solving across various subjects, in everyday life and in any career you may pursue later in life.

There are five core areas which are covered, namely:
Numbers, operations and relationships
Patterns, functions and algebra
Space and shape (geometry)
Measurement
Data handling

Grade 8 Mathematics
  • Decimal Fractions: Addition and Subtraction

    Episode 1

    We will be focusing on addition and subtraction when it comes to decimal fractions. We look at the rules on how to solve decimal fraction problems and the definitions of the terms used.

  • Decimal Fractions: Multiplication, division and percentage.

    Episode 2

    We learn how to calculate decimal fractions, this time by using multiplication, division and percentage of fractions.

  • Numeric Sequence

    Episode 3

    Numeric sequences have to do with numbers arranged in two or more elements to form patterns. By the end of this lesson you will be able to describe and extend the rule that defines numeric patterns and learn techniques that will help you solve mathematical problems.

  • Geometric Sequence

    Episode 4

    A geometric sequence is a sequence of numbers in which each new term (except for the first term) is calculated by multiplying the previous term by a constant value called the constant ratio (𝑟). This lesson will go over how these sequences can be represented in diagrams.

  • Functions and Relations part 1

    Episode 5

    Functions are rules or relationships for which any input values result in one unique output value. By the end of this lesson you will be able to find the input and output values using the rules supplied.

  • Functions and Relations part 2

    Episode 6

    Functions are rules or relationships for which any input values result in one unique output value. By the end of this lesson you will be able to find the input and output values using the rules supplied.

  • Algebraic Expressions

    Episode 7

    This lesson gives insight into algebraic expressions.

  • Algebraic Expressions

    Episode 8

    This lesson will teach you all about terms and how to recognise what separates terms and what brings them together. After that we will learn about polynomials and the different kinds that we will be looking at.

  • Parts of Algebraic Expressions

    Episode 9

    Building on the previous lessons we will proceed to learn about the different parts of an algebraic expression, the constant, the variable and the coefficient. We will then learn more about exponents and how to order expressions.

  • Algebraic Expressions like and unlike terms

    Episode 10

    Algebraic expressions are made up of terms and they are separated by a plus or minus sign. This lesson introduces you to like and unlike terms and how they intersect with addition, subtraction, multiplication and division.

  • Exponents part 1

    Episode 11

    Let’s dive into exponents, this lesson goes over all the rules that will help us solve expressions and equations with exponents in them.

  • Exponents part 2

    Episode 12

    We go over all the rules of exponents and what it means when we raise an expression to another power and how to root an exponent.
