Year 1 Maths: Compare Two Numbers – Up to 20

Introduction

Hello, Year 1! Today, we are going to learn how to compare two numbers. Comparing means looking at two numbers and deciding which one is bigger, smaller, or if they are the same. We will use numbers up to 20.

What Does It Mean to Compare?

When we compare two numbers, we are trying to find out:

• Which number is bigger?
• Which number is smaller?
• Are the two numbers the same?

Key Rules

1. Bigger Numbers: The number that has more is the bigger number. For example, 15 is bigger than 10.
2. Smaller Numbers: The number that has less is the smaller number. For example, 5 is smaller than 8.
3. Same Numbers: If both numbers are equal, we say they are the same. For example, 7 is the same as 7.

Tips and Tricks

• You can use your fingers to help you count numbers!
• Draw pictures or use objects like blocks to compare.
• Remember, when counting, the number that comes first in counting is smaller, and the number that comes later is bigger.

Examples

Let’s compare two numbers: 4 and 7.

1. Bigger or Smaller?
   • 4 is smaller than 7.
   • So, we say 4 < 7 (this means 4 is less than 7).
2. Now let’s look at 10 and 10.
   • Here, both numbers are the same.
   • We say 10 = 10 (this means 10 is equal to 10).
