Understanding Large Numbers and Order

Composing Large Numbers

• Break down large numbers into manageable parts.
• Use place value to read and write:
  • Thousands (1,000)
  • Millions (1,000,000)
  • Billions (1,000,000,000)
• Write out each part and combine:
  • Example: 1,234,567 is "one million two hundred thirty-four thousand five hundred sixty-seven."

Ordinal Numbers

• Indicate position or order in a sequence.
• Formed by adding suffixes:
  • First (1st)
  • Second (2nd)
  • Third (3rd)
• For numbers 4 and above, use:
  • Fourth (4th)
  • Fifth (5th)
  • Sixth (6th), and so on.
• Larger ordinal numbers follow a similar pattern:
  • 21st (twenty-first), 22nd (twenty-second), 23rd (twenty-third), etc.

Numbers Till Hundreds

• Write numbers from 1 to 100 in words:
  • 1-10: one, two, three, four, five, six, seven, eight, nine, ten
  • 11-19: eleven, twelve, thirteen, fourteen, fifteen, sixteen, seventeen, eighteen, nineteen
  • 20-90: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety
• Combine tens and units for numbers 21-99:
  • Example: 42 is "forty-two," 76 is "seventy-six."
• Special case for "hundred":
  • 100 is "one hundred."

Composing Large Numbers

• Large numbers can be simplified by breaking them into sections based on place value.
• Place values include:
  • Thousands, represented by 1,000.
  • Millions, represented by 1,000,000.
  • Billions, represented by 1,000,000,000.
• To articulate large numbers, express each component separately before combining:
  • Example: 1,234,567 reads as "one million two hundred thirty-four thousand five hundred sixty-seven."

Ordinal Numbers

• Ordinal numbers specify the position of an item in a list or sequence.
• Formed by adding appropriate suffixes to cardinal numbers:
  • 1 becomes "first" (1st)
  • 2 becomes "second" (2nd)
  • 3 becomes "third" (3rd).
• For numbers four and higher, the pattern continues with:
  • Fourth (4th), Fifth (5th), Sixth (6th), etc.
• Larger ordinal numbers follow a consistent method:
  • 21st is "twenty-first," 22nd is "twenty-second," and 23rd is "twenty-third."

Numbers Till Hundreds

• Numbers between 1 and 100 should be written in words for clarity:
  • Basic numbers from 1-10: one through ten.
  • Numbers from 11-19 have unique names: eleven through nineteen.
  • Multiples of ten from 20-90 are: twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety.
• For numbers 21-99, combine tens and units with a hyphen:
  • Example: "forty-two" for 42 and "seventy-six" for 76.
• The word "hundred" is special, with 100 written as "one hundred."
