Year 1 Maths: Count Forward and Backward – Up to 100

Introduction

Hello, Year 1! Today, we’re going to learn about counting forward and backward up to 100. Counting is like a fun game where we can jump up and down the number line! Let’s start by understanding what counting forward and backward means.

What Does Counting Forward Mean?

When we count forward, we are going up the number line. For example, if we start at 1 and count forward, we say:

1, 2, 3, 4, 5, …, all the way up to 100!

Key Rule for Counting Forward

• Always add 1 to the last number to get the next number.

Example

If you are at 5 and you want to count forward, just add 1:

• 5 + 1 = 6.

What Does Counting Backward Mean?

Counting backward is like going down the number line. For example, if we start at 10 and count backward, we say:

10, 9, 8, 7, 6, …, all the way down to 1!

Key Rule for Counting Backward

• Always subtract 1 from the last number to get the previous number.

Example

If you are at 7 and you want to count backward, just take away 1:

• 7 – 1 = 6.

Tips and Tricks

• Use Your Fingers: You can use your fingers to help you count. Each finger can represent a number!
• Count in Groups: Practice counting by 2s, 5s, or 10s. This makes it easier and faster.
• Sing Songs: There are many counting songs that can help you learn to count forward and backward. They make learning fun!
