Your personal notebook

By Rebecca Robb Benne

We use numbers all the time: when we enter a pin number to open our phone, when we check the time and date, when we buy a bus ticket, and when we keep track of our favourite sport teams’ scores.

In this topic, you will learn about the ways we use numbers to count, to measure, to organize time, to bring order, and to solve problems. You will also learn what different numbers mean in different cultures, and you will discover how numbers are used in popular books and stories.
