Number and Numeration Systems

1. Modelling Number Quantities

Modelling in mathematics is a way that we represent real life phenomenon using mathematical ideas and concepts. In this lesson, we will learn how to model number quantities using multi-base blocks, graph sheets and token currency notes.

We will also learn how to use multiples of 10s, 50s, 100s and 200s to represent numbers in various ways.
