Year 1 Maths: Write Subtraction Sentences – Numbers up to 10

Introduction to Subtraction

Hello, class! Today, we are going to learn about subtraction. Subtraction is when we take away some things from a group. It helps us find out how many are left.

What is a Subtraction Sentence?

A subtraction sentence is a way to show what we are taking away. We write it using numbers and the minus sign (-). For example, if we have 5 apples and we eat 2, we can write this as:

$$5 – 2 = 3$$

This means we started with 5 apples, took away 2, and now we have 3 apples left.

Key Rules for Writing Subtraction Sentences

1. Start with a number: This is how many you have at the beginning.
2. Use the minus sign (-): This shows that you are taking away.
3. Write the number you are taking away: This is how many you will subtract.
4. Equals sign (=): This shows what is left after you subtract.

Tips and Tricks

• Use objects: You can use toys, blocks, or your fingers to help you see the numbers.
• Draw pictures: Sometimes drawing can help you understand better.
• Practice with real-life examples: Count things around you and try to write subtraction sentences.
