Chapter 10 — Data and Information
We see and use information every day. We may count how many children like apples, which colour is most popular, or how many books are on a shelf. The information we collect can help us understand things more clearly.
In this chapter, you will learn what data means, how to collect simple information, how to sort information, and how to organise information using simple tables and charts.
Why This Chapter Matters
Data helps us organise information and answer simple questions. When information is collected and arranged clearly, it becomes easier to count, compare and understand.
These steps help us turn simple information into something that is easy to understand.
These skills are useful in everyday life and provide a foundation for learning more about tables, charts, graphs and data in later classes.
What You Will Learn
- What data means.
- How to collect simple information.
- How to sort information into groups.
- How to organise information in a simple table.
- How to read information from a simple table.
- What a simple chart shows.
- How to read simple charts.
- How to answer simple questions using information.
Before You Begin
Before starting this chapter, you should be comfortable with counting numbers and comparing small quantities.
You will use these skills to count, group and compare information while learning the new concepts in this chapter.
Understanding the Learning Sequence
The lessons move from understanding what data is to collecting information, sorting it into groups, organising it in tables and finally reading simple charts.
This sequence helps you first understand information before organising it and using it to answer simple questions.

Quick Revision
Data is information that we collect. We can collect simple information by asking questions or observing objects and people.
Information can be sorted and organised using tables. Simple charts can also help us see, count and compare information easily.
