Introduction

In Year 7 Maths, one of the topics students study is understanding how to write and recognise numbers in word form. This involves converting numbers written numerically (such as 325) into words (“three hundred and twenty-five”) and vice versa. Mastering this skill helps students better understand number values and how they are structured.

Why It’s Important

Being able to express numbers in word form allows students to develop their number sense. It’s a fundamental skill used in everyday life, from writing cheques to reading large numbers in books and articles. It also strengthens their understanding of place value, which is crucial for more advanced mathematics.

Key Concepts

1. Understanding Place Value: The position of a digit in a number determines its value.
2. Grouping by Hundreds, Thousands, and Millions: Recognising how numbers are grouped makes reading and writing them easier.
3. Correct Use of Hyphens: In word names for numbers, numbers between 21 and 99 (except multiples of ten) use hyphens (e.g., twenty-three).
4. Handling Large Numbers: Knowing how to break larger numbers into smaller, manageable chunks helps in reading them accurately.

Let’s practise this with questions designed at three different levels: easy, medium, and hard.
