1. 1. WRITING 1 to 999 – STEP 1 Learn to write numbers from 1 to 9. This is where it all starts. Learn these, and the rest gets much easier:
2. 2. WRITING 1 to 999 – STEP 2 Write numbers from 10 to 19. Do you see how many of them look just like the numbers above, plus "teen" at the end? "Sixteen" (16) just means "six and ten" (6 + 10).
3. 3. WRITING 1 to 999 – STEP 3 Count in tens from 20 to 90. Here's how to write 20, 30, 40, and so on all the way to 100. You can recognize these numbers because they end in "ty" except 100).
4. 4. WRITING 1 to 999 – STEP 4 Combine words to write more numbers. Now you can write any number from 1 to 100. Let's see how it works for the number 42: 42 is written with two numbers: 4 and 2. 2 is in the ones place, so this just equals 2. Write this as two. 4 is in the tens place, so this is actually 40. Write this as forty. Write the two parts together: forty two. Don't forget the - sign between them.
5. 5. Grammar Check Forty two or Forty-two? Regardless of where they appear in a number, hyphenate all compound numbers between 21 and 99 (not 30, 40, 50, 60, 70, 80, and 90) such as 42. In other words: Hyphenate all numbers between twenty-one and ninety-nine, except those divisible by ten even if the compound number is preceded or succeeded by numbers that do not require hyphens.
6. 6. WRITING 1 to 999 – STEP 5 Count by hundreds. This part's easy if you remember the basics. Just write the number as usual and add "hundred:"
7. 7. WRITING 1 to 999 – STEP 6 Write any number from 100 to 999. Just write the hundreds place then and then the rest of the number. 120 = one hundred and twenty 405 = four hundred and five 556 = five hundred and fifty-six 999 = nine hundred and ninety-nine
8. 8. WRITING LONG NUMBERS– STEP 1 Understand place values. We can tell what each digit in a number means based on where it is. Here's what the first 9 place values are called: 1 → 10 → 100 → 1,000 → 10,000 → 100,000 → 1000,000 → 10,000,000 → 100,000,000 → the ones place. the tens place. the hundreds place. the thousands place. the ten thousands place. the hundred thousands place. the millions place. the ten millions place. the hundred millions place.
9. 9. WRITING LONG NUMBERS– STEP 2 Add commas to long numbers. Start from the right side of the number, at the ones place. Count three digits to the left, then add a comma. Keep separating the number in groups of three For example turn 458735 into 458,735 and 1510800 as 1,510,800 and 56378403987 as 56,378,403,987
10. 10. WRITING LONG NUMBERS– STEP 3a Identify the place value(s) of each set : For example: 4,517,801 4,517,801 } } } millions thousands ones This number in words is four million, five hundred and seventeen thousand, eight hundred and one
11. 11. WRITING LONG NUMBERS– STEP 3b Identify the place value(s) of each set : For example: 23,708,219,965 23,708,219,965 } } } millions thousands ones This number in words is twenty-three billion, seven hundred and eight million, two hundred and nineteen thousand, nine hundred and sixty-five } billions
12. 12. OR use a place value table such as this OR this
13. 13. Example: write 5467320 in words Start by writing the number in the table so the last digit is in the ones column 5 4 6 7 3 2 0 5 4 6 7 3 2 0 Sometimes it may be easier to write the number starting with the ones digit
14. 14. Example A: write 5467320 in words 5 4 6 7 3 2 0 To write out this number starting with the left most block of three that has a digit in it (in this case it is the millions) } five million, four hundred and sixty-seven thousand, three hundred and twenty
15. 15. Example B: write 23,405,021,009,204 in words 1 0 0 9 2 0 4 twenty-one million, nine thousand, two hundred and four 2 3 4 0 5 0 2 twenty-three trillion, four hundred and five billion,
16. 16. Example C: write 291,000,040,100,006 in words 0 0 0 0 0 0 6 forty million, and six 9 1 0 0 0 0 4 two hundred and ninety-one trillion, 2
