Whole Numbers (Contd)

Grade 4

Topic: Counting and Writing Numbers up to One Million

1. Counting from Thousand to One Million

  • Counting in Thousands:
    • Start from 1,000 (one thousand) and keep adding 1,000 each time: 1,000, 2,000, 3,000, and so on.
    • Example: If you count every 1,000 from 1,000 to 10,000, you will get 1,000, 2,000, 3,000, 4,000, 5,000, 6,000, 7,000, 8,000, 9,000, and 10,000.
  • Counting in Millions:
    • Start from 1,000,000 (one million) and keep adding 1,000,000: 1,000,000, 2,000,000, 3,000,000, and so on.
    • Example: If you count every 1,000,000 from 1,000,000 to 5,000,000, you will get 1,000,000, 2,000,000, 3,000,000, 4,000,000, and 5,000,000.

2. Writing Numbers up to One Million

  • Writing Large Numbers:
    • Write each number by grouping them in thousands and millions.
    • Example:
      • 4,000: Four thousand
      • 25,000: Twenty-five thousand
      • 143,000: One hundred forty-three thousand
      • 1,000,000: One million

3. The Place Value of Numbers up to One Million

  • Understanding Place Value:
    • Each digit in a number has a place value, which tells you how much that digit is worth.
    • Example: In the number 352,478:
      • 3 is in the Hundreds Thousand place (300,000)
      • 5 is in the Ten Thousand place (50,000)
      • 2 is in the Thousand place (2,000)
      • 4 is in the Hundreds place (400)
      • 7 is in the Tens place (70)
      • 8 is in the Ones place (8)

4. Counting Numbers in Thousands and Millions

  • Counting in Thousands:
    • Use 1,000 as a base to count higher: 1,000, 2,000, 3,000, etc.
    • Example: To count up to 5,000, you say: 1,000, 2,000, 3,000, 4,000, and 5,000.
  • Counting in Millions:
    • Use 1,000,000 as a base: 1,000,000, 2,000,000, 3,000,000, etc.
    • Example: To count up to 3,000,000, you say: 1,000,000, 2,000,000, and 3,000,000.

5. Writing Numbers in Words up to One Million

  • Writing in Words:
    • Convert numbers into words by breaking them into thousands and millions.
    • Example:
      • 76,432: Seventy-six thousand four hundred thirty-two
      • 1,234,567: One million two hundred thirty-four thousand five hundred sixty-seven

6. Identifying Place Value of Numbers up to One Million

  • Finding Place Value:
    • Determine what each digit represents in the number.
    • Example: In 582,734:
