Grade 9 Mathematics – Number Systems

Grade 9 Mathematics – Number Systems

COURSE OVERVIEW

In this course, learners will strengthen their understanding of the number system and develop the skills needed to work confidently with different types of numbers.

Learners will explore natural numbers, whole numbers, integers, rational numbers, irrational numbers and real numbers, while investigating how these number sets are related.

The course also develops learners’ ability to work with factors, multiples, prime numbers and number properties, and to apply number concepts when solving mathematical problems.

Through video lessons, worked examples, quizzes, practice activities and a mastery test, learners will develop the number skills required for more advanced Grade 9 Mathematics.
