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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
OR use a place value table such as this
OR this

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.
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.
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.
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,
