Fun with Numbers: Understanding 1 to 20 in Class 1 Maths
Welcome to the magical world of numbers! In Class 1 Maths, one of the first and most important chapters children learn is “Numbers from 1 to 20.” This topic lays the foundation for all future math learning. If children grasp this concept well, they’ll be confident in solving bigger problems ahead.
In this post, we’ll explore how to teach and learn numbers from 1 to 20 in fun, simple, and effective ways. Whether you’re a parent, teacher, or a curious child, this guide is for you!
🎯 Why is Learning 1 to 20 Important?
Numbers 1 to 20 may seem small, but they are the building blocks of maths. Children learn:
- How to count objects
- How to write numbers
- Number names (one, two, three…)
- Comparing numbers (greater than, less than, equal)
- Simple addition and subtraction
Once these are clear, moving to 50, 100, and beyond becomes easier.
🌈 Learning Numbers 1 to 20 – Step-by-Step
Let’s break down the process to make it fun and easy:
1️⃣ Step 1: Recognizing Numbers
Children must first see and say numbers correctly.
🧸 Activity:
- Show flashcards with numbers 1 to 20.
- Say the number aloud: “This is one, this is two…”
- Ask children to repeat and clap while saying it.
🎨 Craft Idea:
Make a “Number Train” on the wall. Each coach has one number. Let kids decorate the train with drawings (1 apple, 2 cats, 3 stars…).
✍️ Step 2: Writing Numbers
After recognizing, children should practice writing numbers neatly.
Practice Sheet:
- Use dotted lines for tracing numbers 1 to 20.
- Start with 1 to 5, then slowly go up to 20.
Fun Tip:
Give star stickers or smiley stamps for every correct attempt. Praise their effort!
🔤 Step 3: Number Names (One to Twenty)
Children also learn how to spell and read number words.

| 13 | Thirteen |
| 14 | Fourteen |
| 15 | Fifteen |
| 16 | Sixteen |
| 17 | Seventeen |
| 18 | Eighteen |
| 19 | Nineteen |
| 20 | Twenty |
💡 Tips:
- Sing songs that include number names
- Use flashcards: “Show me SEVEN”
🔢 Step 4: Counting Objects
Now, connect numbers to real things.
🧁 Object Counting:
- Place 5 biscuits on a plate. Ask: “How many biscuits are there?”
- Give a worksheet with pictures of animals, fruits, etc. and ask children to count and write the number.
🍎 Example:
Count and write: 🍎🍎🍎 = 3 apples
🔄 Step 5: Comparing Numbers
Now introduce Greater than ( > ), Less than ( < ), and Equal to ( = ).
🐘 Fun Trick:
Use the hungry crocodile story!
- Crocodile always eats the bigger number.
Example: 6 > 3 (So the mouth opens towards 6)
🌟 Activity:
- Show two numbers: 12 and 9
Ask: “Which number is bigger?”
Answer: 12 > 9
➕ Step 6: Simple Addition
Start adding small numbers using fingers or objects.
Example:
3 + 2 = ?
Take 3 pencils, add 2 more. Count all = 5
🎲 Game:
Roll two dice and add the numbers. Write down the answer!
➖ Step 7: Simple Subtraction
Teach subtraction as “taking away.”
🍬 Story:
“You have 5 candies. You eat 2. How many left?”
5 – 2 = 3
Activity:
Use fingers to subtract. Start with 10 fingers, fold some, count what’s left.
🧠 Bonus: Place Value (Tens and Ones)
Show numbers like 12 as:
- 1 Ten and 2 Ones
- Use ice-cream sticks, straws or bundles
Example:
💐 10 flowers tied in a bunch = 1 Ten
Loose flowers = Ones
So, 1 bunch + 3 loose = 13
