Whole Numbers
Gr 9

The Grade 9 Whole Numbers module reinforces the fundamental numerical skills that underpin all higher-level mathematics. This chapter helps learners work confidently with large values, rounding, estimation, and multi-step calculations, ensuring they have a strong foundation before progressing to more complex algebra and number theory.

Lessons cover place value, expanded notation, rounding to various degrees of accuracy, estimating calculations, and performing operations with whole numbers using efficient methods. Learners also explore problem-solving techniques, including working with multi-step word problems and interpreting numerical information in real-life contexts. Clear explanations and guided examples help students build confidence and accuracy.

By the end of this module, learners will be able to operate with whole numbers fluently, apply estimation and rounding appropriately, and solve practical problems with greater efficiency—forming a crucial base for Grade 9 and senior-phase mathematics.
