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.

2. Comparing Whole Numbers

Which numbers can we consider as whole numbers? Can you define in your own words what whole numbers are?

Before we look at what whole numbers are, let's first look at some basic definitions of some types of numbers that we have in mathematics.

3. Rounding Whole Numbers

Learn to round (off, up and down) whole numbers up to over 1,000,000,000 to the nearest hundred-thousands, ten-thousands, thousands, hundreds, etc.

Also, learn to express whole numbers to given significant figures.

4. Rounding Decimals

Learn to round (off, up and down) decimals to the nearest tenths, hundredths, thousandths etc.

5. Decimals to Significant Figures and Decimal Places

In this lesson, we will learn about writing numbers to given significant figures and decimal places. We will also learn about when the digit zero (0) is significant within a number.
