For parents, there are 12 downloadable practice worksheets that they can use for their kids.

In this article, you will learn:

  • Large numbers - Introductions
  • Learning 1 - 7 digit numbers and the different operations - comparing and ordering, expand numbers, place value and face value, etc.

Introduction to Large Numbers

As you learn large numbers, they have a pattern of place value. Here we’ll learn about the range of large numbers from 1 to 7 digits - from the smallest in this range to the largest.

Place Value and Digits

Each digit has a special place or position in a number. These places tell us what value the digit holds in the number. For instance, in the number 5,432, the place values are:

Thousands 

Hundred 

Tens 

Ones

5

4

3

2

 

This pattern will help us understand why numbers like 500 and 5,000 are different.

Learning 1- to 7-digit Numbers

One-Digit Numbers

1-digit numbers are the simplest, from 1 to 9. These numbers only have the Ones place.

Image of Large Numbers - 1 to 9

A 1-digit number has only one digit, like 1, 2, 3, up to 9.

Example:

  • The number 7 is a 1-digit number. It stands alone, representing seven objects.
  • Smallest One-Digit Number: 1 
  • Greatest One-Digit Number: 9

Practice Questions:

1. Which of the following is a 1-digit number?

Two-Digit Numbers

When we go past 9, we get to two-digit numbers, which go from 10 to 99. Now, we need two digits! These numbers have two places: Tens and Ones.

Image of Large Numbers, 9 ones + 1 ones = 1 Tens

Example:

  • The number 42 has 4 Tens and 2 Ones.
  • 4 Tens means 40 and 2 Ones means 2. Together, 42 means forty-two.
  • Smallest Two-Digit Number: 10
  • Greatest Two-Digit Number: 99

Six-Digit Numbers

Six-digit numbers go from 100,000 to 999,999. These numbers are called lakhs or hundred thousands because they add the Hundred Thousands place.

  • Smallest Six-Digit Number: 100,000
  • Greatest Six-Digit Number: 999,999

Explanation:

  • The smallest 6-digit number is 1,00,000.
  • The smallest 5-digit number is 10,000, and the largest 5-digit number is 99,999.

When we add 99,999 + 1, we get 1,00,000, which is read as one lakh.

  • 10 ten thousands make 1 lakh.
  • The greatest 6-digit number is 9,99,999, read as Nine lakh, ninety-nine thousand, nine hundred ninety-nine.

This number can be shown in a place value chart.
