Sita has 5 apples. We write the number as 5. We can also write it as a word: five. Every number has a name!
When we write a cheque at the bank, we write the amount in words. When we read a storybook, numbers are written as words. Learning number names helps us read and write numbers in both ways.

Notice: eleven and twelve are special names. Thirteen to nineteen all end in "-teen". That is why we call them "teen numbers"!
Tens: 10, 20, 30, 40, 50
These are the "round" numbers — they end in zero. Learn their names:
Number

50
fifty

Be careful! It is "forty" (NOT "fourty"). This is a common spelling mistake!
Numbers 21 to 50 — How to Write Their Names
For numbers 21 to 50, we combine the tens name and the ones name with a hyphen:
Write the number name of 37:
Step 1: The tens digit is 3 → thirty
Step 2: The ones digit is 7 → seven
Step 3: Combine: thirty-seven
Write the number name of 48:
Step 1: The tens digit is 4 → forty
Step 2: The ones digit is 8 → eight
Step 3: Combine: forty-eight
