How to compare numbers up to 20 in Grade 1 math

📚 What Does Comparing Numbers Mean?

Comparing numbers in Grade 1 math simply means figuring out if one number is greater than (bigger than), less than (smaller than), or equal to (the same as) another number. We usually compare whole numbers, like 1, 2, 3, all the way up to 20 in this case!

Think of it like having two groups of toys. Comparing numbers helps you decide which group has more, fewer, or the same number of toys. Easy peasy! 😄

➕ Greater Than

Greater than means one number is bigger than the other. We use the '>' symbol to show this.

• 🍎 Example: 7 > 3 (7 is greater than 3)
• 💡 How to remember: Imagine the '>' symbol as an alligator's mouth, always wanting to eat the bigger number! 🐊
• ✍️ Real-world Example: If you have 8 cookies and your friend has 5, you have a greater number of cookies.

➖ Less Than

Less than means one number is smaller than the other. We use the '<' symbol to show this.

• 🍇 Example: 2 < 6 (2 is less than 6)
• 🤔 How to remember: Think of it as the alligator's back – the smaller number is behind it!
• 🌱 Real-world Example: If you have 4 pencils and your classmate has 9, you have a less number of pencils.

➗ Equal To

Equal to means both numbers are the same. We use the '=' symbol to show this.

• ⚽ Example: 5 = 5 (5 is equal to 5)
• 🤝 How to remember: They are the same, just like twins!
• 🎂 Real-world Example: If you and your sibling each have 3 cupcakes, you have an equal number of cupcakes.
