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

Grade 8 Mathematics
  • Decimal Fractions Part 1: Additions and Subtraction

    Episode 1

    This lesson focuses 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 Part 2: Multiplication and Division

    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 Part One

    Episode 7

    This lesson gives more insight into using terms of expressions to solve an algebraic equation.

  • Algebraic Expressions Part Two

    Episode 8

    This lesson will teach you all about terms and how to recognize 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

    An exponent is the number of times that a number is multiplied by itself. This lesson will focus more on calculations thus you will need to go back to revising the laws of exponents.

  • Exponents Part 1

    Episode 12

    In this lesson, we will look through all the exponent examples and how to solve expressions with exponents.

  • Electrochemical reactions

    Episode 13

    Explore the fascinating interplay of electricity and chemical reactions, investigating how electrons flow between substances to create electricity or drive chemical changes.

  • Electric Circuits: internal resistance

    Episode 14

    Delve into how internal resistance affects the flow of current within electric circuits, exploring its impact on voltage and power distribution.

  • Introduction to electrodynamics
