Let’s explore some important topics from the Class 4 number system worksheet.

Numbers Beyond 9999

Numbers greater than 9,999 are called large numbers. In Class 4, children learn to read and write numbers up to six digits.

Examples

  1. 12,345 → Twelve thousand three hundred forty-five
  2. 45,678 → Forty-five thousand six hundred seventy-eight
  3. 89,999 → Eighty-nine thousand nine hundred ninety-nine

These numbers help children understand how numbers grow beyond four digits.

Six Digit Numbers

A six-digit number has digits from the ones place to the hundred-thousands place.

Examples

  1. 1,25,678 → One lakh twenty-five thousand six hundred seventy-eight
  2. 3,45,210 → Three lakh forty-five thousand two hundred ten
  3. 9,99,999 → Nine lakh ninety-nine thousand nine hundred ninety-nine

The smallest six-digit number is 1,00,000, and the largest six-digit number is 9,99,999.

Periods

In the Indian number system, digits are grouped into periods using commas to make large numbers easier to read.

The three main periods are:

  • Ones Period
  • Thousands Period
  • Lakhs Period

Examples

  1. 4,56,321
  2. 7,89,654
  3. 1,25,430

These commas help us read numbers correctly.

Indian Place Value Chart

The Indian Place Value Chart helps us understand the position of each digit in a number.

Examples

  1. 3,45,678
  2. 7,20,451
  3. 5,10,230

Each digit changes value depending on its place.

Face Value & Place Value

  • Face Value: The actual digit itself.
  • Place Value: The value of the digit based on its position.

Examples

  1. In 45,678, digit 5
    • Face value = 5
    • Place value = 5,000
  2. In 3,26,419, digit 2
    • Face value = 2
    • Place value = 20,000
  3. In 7,81,245, digit 8
    • Face value = 8
    • Place value = 80,000

Expanded Form & Standard Form

Expanded form shows a number as the sum of its place values.

Examples

  1. 45,678
    = 40,000 + 5,000 + 600 + 70 + 8
  2. 2,34,567
    = 2,00,000 + 30,000 + 4,000 + 500 + 60 + 7
  3. 1,20,345
    = 1,00,000 + 20,000 + 300 + 40 + 5

Standard form means writing the number in normal digit form – Ex: 24, 779

Comparing Large Numbers

When two numbers have different number of digits, the number with less number of digits is always less than the number with more number of digit.

Example: 4560 < 11,390

When the two numbers have the same number of digits, we check the digits from left to right. First compare the digits in lakhs place, then compare the digits in ten thousands place, then compare the digits in thousands place and so on till units place.

Examples

  1. 4,56,789 > 4,12,345
  2. 3,25,678 < 3,45,210
  3. 9,10,234 > 8,99,999

The number with the larger digit in the highest place is greater.

Ascending & Descending Order

Ascending order means from smallest to greatest.

Descending order means from greatest to smallest.

Examples

Ascending order:

  1. 23,456, 34,567, 45,678
  2. 1,25,430, 2,34,567, 3,21,456
  3. 5,10,230, 6,21,345, 7,89,654

Descending order:

  1. 45,678, 34,567, 23,456
  2. 3,21,456, 2,34,567, 1,25,430
  3. 7,89,654, 6,21,345, 5,10,230

Successor & Predecessor

Successor: number that comes after a number. Successor of a number = number + 1

Predecessor: number that comes before a number. Predecessor of a number = number −1

Examples

  1. Successor of 45,678 → 45,679
  2. Predecessor of 1,00,000 → 99,999
  3. Successor of 2,45,999 → 2,46,000

Building Numbers

Sometimes we create numbers using given digits by arranging digits. 

Examples

Digits: 3, 5, 7, 9

  1. Largest number → 9,753
  2. Smallest number → 3,579
  3. Another number → 7,953

This helps children understand digit arrangement.

Rounding Numbers

Rounding Off to nearest 10

To round a number to the nearest 10, look at the ones digit. If it is 5 or more, round up to the next ten; if it is 4 or less, round down to the previous ten.

Examples:

  1. 67 → 70
  2. 124 → 120
  3. 539 → 540

Rounding Off to nearest 100

To round a number to the nearest 100, check the tens digit. If the tens digit is 5 or more, round up to the next hundred; if it is 4 or less, round down.

Examples:

  1. 456 → 500
  2. 1,245 → 1,200
  3. 3,678 → 3,700

Rounding to nearest 1000

To round a number to the nearest 1000, look at the hundreds digit. If the hundreds digit is 5 or more, round up to the next thousand; if it is 4 or less, round down.

Examples:

  1. 4,567 → 5,000
  2. 12,345 → 12,000
  3. 8,789 → 9,000

These concepts are commonly practised in large numbers worksheet for class 4 and help students improve estimation skills.
