🔢 Numbers, Age, and Phone Numbers

In this fun lesson, you will learn numbers from 1 to 100. You will also learn how to say your age and your phone number.

Numbers 1 to 20

First, let's learn the basic numbers. Numbers one to ten are easy: one, two, three, four, five, six, seven, eight, nine, ten. Numbers eleven to twenty are special words you need to memorize, like eleven, twelve, fifteen, and twenty.

I have three cats.The number is three.

She is twenty years old.The number is twenty.

Tens (30 to 100)

To count by tens, we add 'ty' to the end. For example: thirty, forty, fifty, sixty, seventy, eighty, ninety, and one hundred. To make numbers like 35 or 42, just say the ten first and then the small number: thirty-five, forty-two.

The book costs fifty dollars.The number is fifty.

My grandfather is seventy-five.The number is seventy-five.

Saying Your Age and Phone Number

To say how old you are, use the verb 'to be'. Say 'I am' and then your age. To share your phone number, say each digit one by one. For example, 555-1234 is five-five-five, one-two-three-four.

I am twenty-five years old.This is how you say your age.

My phone number is 555-4321.This is how you share your phone number.
