In today’s video, we will learn **how to count, write and pronounce numbers**. Counting is also a very important skill that you will use in many situations, such as counting objects, money, time, and more. It is also a foundation of arithmetic, which is a branch of mathematics that deals with adding, subtracting, multiplying, and dividing numbers.

### How to count from 1 to 10

We will use the decimal system, which is based on the number 10. This means that we will group the numbers from 1 to 10. Let’s start with the first ten numbers, **from 1 to 10**. Remember to repeat after me. They are:

From 1 to 10 |
---|

1 – one |

2 – two |

3 – three |

4 – four |

5 – five |

6 – six |

7 – seven |

8 – eight |

9 – nine |

10 – ten |

### Let’s count from 11 to 20!

Great job! Now, let’s move on to the next ten numbers, **from 11 to 20**. These are a bit tricky, because they have irregular spellings and pronunciations. They are:

From 11 to 20 |
---|

11 – eleven |

12 – twelve |

13 – thirteen |

14 – fourteen |

15 – fifteen |

16 – sixteen |

17 – seventeen |

18 – eighteen |

19 – nineteen |

20 – twenty |

Well done! Now, you may notice a pattern here. From 13 to 19, the numbers end with “-teen“, which sounds like “ten”. This is because the numbers are formed by adding 10 to the numbers from 3 to 9. For example, 13 is 3+ 10, so we say “thirteen”. 14 is 4 + 10, so we say “fourteen”. And so on.

### Let’s now try from 20 to 99!

**From 20 to 90**, the numbers end with “-ty“, which sounds like “tee”. This is because these numbers are formed by multiplying 10 by the numbers from 2 to 9. For example, 20 is 2 x 10, so we say “twenty”. 30 is 3 x 10, so we say “thirty”. And so on.

Let’s practice the numbers from 20 to 90. They are:

From 20 to 99 |
---|

20 – twenty |

30 – thirty |

40 – forty |

50 – fifty |

60 – sixty |

70 – seventy |

80 – eighty |

90 – ninety |

Excellent! Now, let’s form the numbers from 21 to 99: we simply combine the numbers from 20 to 90 to the numbers from 1 to 9. For example, 21 is 20 + 1, so we say “twenty-one”. 35 is 30 + 5, so we say “thirty-five”. 76 is 70 + 6, so we say “seventy-six”. And so on.

Let’s practice some of the numbers **from 21 to 99**. Please repeat after me:

From 21 to 99 |
---|

22 – twenty-two |

27 – twenty-seven |

43 – forty-three |

58 – fifty-eight |

64 – sixty-four |

75 – seventy-five |

89 – eighty-nine |

94 – ninety-four |

### What about counting from 100 to 999?

Very good! To form the number 100, we use the word “hundred“. 100 is 10 x 10, so we say, “one hundred”. We can also use the word “hundred” to form numbers from 101 to 999, by combining it with the numbers from 1 to 9, using the word “and”. For example, 101 is 100 + 1, so we say, “one hundred and one”. 150 is 100 + 50, so we say, “one hundred and fifty”. 237 is 200 + 30 + 7, so we say, “two hundred and thirty-seven”. And so on.

Let’s practice some examples of the numbers from **100 to 999**. Please repeat after me:

From 100 to 999 |
---|

100 – one hundred |

105 – one hundred and five |

135 – one hundred and thirty-five |

200 – two hundred |

250 – two hundred and fifty |

300 – three hundred |

350 – three hundred and fifty |

400 – four hundred |

415 – four hundred and fifteen |

500 – five hundred |

523 – five hundred and twenty-three |

600 – six hundred |

650 – six hundred and fifty |

700 – seven hundred |

715 – seven hundred and fifteen |

716- seven hundred and sixteen |

800 – eight hundred |

890 – eight hundred and ninety |

891- eight hundred and ninety-one |

892- eight hundred and ninety-two |

900 – nine hundred |

990 – nine hundred and ninety |

999 – nine hundred and ninety-nine |

### And, finally… from 1000 to 9999!

Finally, to form the numbers **from 1000 to 9999**, we use the word “thousand“. 1000 is formed by taking 10 x 100, so we say, “one thousand”. We can also use the word “thousand” to form numbers from 1001 to 9999, by combining it with the numbers from 1 to 999, using the word “and”. For example, 1001 is 1000 + 1, so we say, “one thousand and one”. 2345 is 2000 + 300 + 40 + 5, so we say, “two thousand three hundred and forty-five”. And so on.

Let’s practice some examples of the numbers from 1000 to 9999. Please repeat after me:

From 1000 to 9999 |
---|

1000 – one thousand |

1005 – one thousand and five |

1095 – one thousand and ninety-five |

2000 – two thousand |

2005 – two thousand and five |

3000 – three thousand |

3995 – three thousand nine hundred and ninety-five |

5000 – five thousand |

6000 – six thousand |

6915 – six thousand nine hundred and fifteen |

7000 – seven thousand |

8000 – eight thousand |

8995 – eight thousand nine hundred and ninety- five |

9995 – nine thousand nine hundred and ninety-five |
