Performance objectives

• Identify the place value of digits in whole numbers up to 1,000,000.
• Read and write whole numbers in standard and expanded forms.
• Compare and order whole numbers.
• Solve real-life problems using place value.

Lesson summary

This lesson builds upon learners' prior knowledge of place value with smaller numbers and extends it to handle much larger numbers, up to the billions. Understanding how to read and write large numbers is a fundamental skill essential for everyday life. In Ghana, we encounter large numbers when we talk about our country's population, the national budget in Ghana Cedis, distances between stars, or even large business transactions. This lesson will equip learners with the confidence to understand, read, and write these large numbers accurately.

Lesson notes

A. The Place Value System

Our number system is a base-10 system, which means it uses ten digits (0, 1, 2, 3, 4, 5, 6, 7, 8, 9). The value of a digit depends on its position or place in a number. This position is called its place value.

To make large numbers easier to read, we group the digits into sets of three, starting from the right. Each group is called a period or a family. The periods have names: Units, Thousands, Millions, Billions. We separate these periods with commas (,) or spaces.

Let's look at a place value chart that goes up to the billions.
