Numbers 10,000 - 1,000,000: Lesson for Kids

Instructor: Yuanxin (Amy) Yang Alcocer

Amy has a master's degree in secondary education and has taught math at a public charter high school.

You may not think that you'll ever get to use numbers this large, but knowing how to count these large numbers is important as you'll come across numbers this high at work and on math tests.

Large Numbers

In this lesson, you'll learn about your large numbers 10,000 to 1,000,000. Just look at all those zeroes! The more zeroes you see, the larger your numbers. You may not think that you'll ever get to use these numbers since they are so big. But these numbers are used every day in the real world. For example, your parents most likely are making money that adds up to a number somewhere in this range. One day, you'll be dealing with numbers this large too.

It's hard to visualize numbers this large since it means that you have a lot of something. But, you can break it up into smaller groups of numbers that you do know. For example, the number 10,000 can be broken into 100 groups of 100 each. You know how much 100 is. So, picture 100 groups of 100 candies, and you'll have 10,000. Isn't that a lot of candies?

Now, the number 1,000,000 is much, much larger than 10,000. If you can picture 100 groups of 100 candies each, then the number 1,000,000 is 100 of those 100 groups! Your candies have just increased dramatically now!

Number Names

These large numbers that you are learning about follow the same naming pattern that you already know. For example, when you have 100, it is called one hundred. 200 is called two hundred. Whenever you have three digits, you are in the hundreds. When you get to 1,000, it is called one thousand. 2,000 is called two thousand, and so on. When you reach 10,000, you continue your pattern and call it ten thousand. So, 11,000 is called eleven thousand, 12,000 is called twelve thousand, and so on. 100,000 continues that pattern, and you call it one hundred thousand. It isn't until you reach 1,000,000 that you have a new name. This number is called one million. So, 2,000,000 is called two million. So, million is when you have 7 digits.

To say any of these numbers, you begin with the largest digit and work your way to the right. So, 450,290 is four hundred fifty thousand, two hundred ninety.

Counting by 10

A good skill to have when it comes to these numbers is being able to count by 10 all the way up to 1,000,000. You remember that when you count by 10, you are skipping by 10s. You begin with 10, and you skip 10 to get to 20. Then, you go to 30, then 40. You'll always have a zero at the end. Every time you reach the digit 9, your 9 turns back into a 0, and you add a 1 to the digit to the left of your 9. If there is no digit to the left of the 9, then you'll have to add a 1 in that spot, increasing the number of digits you have by 1, so your 90 turns into 100. When you reach 190, your 9 turns into 0, and you add 1 to that digit to the left of your 9, so 190 turns into 200 when counting by 10s. 290 turns to 300, 390 turns into 400, and so on.

Counting up to 1,000,000 uses the same process except you now have way more digits to count with.

If you start with 10,000, you count like this:

  • 10,000
  • 10,010
  • 10,020
  • ….
  • 10,090
  • 10,100
  • 10,110
  • 10,990
  • 11,000
