# Looking at the Thousands Column

Congratulations! You made it to**one hundred**(100) in our previous section. The same rules that applied to the small numbers continue to work as you now work with a third column of numbers. When you move from a "9" to a "0" the column to the left goes up one value. The only difference is that you are now working with three columns of numbers, not two. Those columns are labeled the

**ones**,

**tens**, and

**hundreds**columns.

**Example:**

459 - 4 in the hundreds, 5 in the tens, and nine in the ones.

723 - 7 in the hundreds, 2 in the tens, and 3 in the ones.

# Some Sample Series

Just remember that when you move from "9" to a "0" the number in the column to the left increases by one value. Let's look at some example series...18, 19, 20, 21

88, 89, 90, 91

And now with values over 100...

118, 119, 120, 121

188, 189, 190, 191

478, 479, 480, 481

628, 629, 630, 631

And with values that cross the hundreds borders. Look at the way the number in the hundreds column goes up one and the rest of the numbers turn to "0."

98, 99, 100, 101, 102

298, 299, 300, 301, 302

598, 599, 600, 601, 602

898, 899, 900, 901, 902

And finishing off the even thousand (1,000) you just need to add a one in the thousands column to the left.

996, 997, 998, 999, 1,000

# Looking at the Words

This is also easy stuff if you mastered naming numbers from one to one hundred. When you deal with numbers between one hundred (100) and**one thousand**(1,000) you will just need to add a hundreds value before the rest of your number. If you're dealing with even hundreds it's like this...

100 - One hundred.

200 - Two hundred (not hundreds).

500 - Five hundred.

800 - Eight hundred.

Now just add what you already know about naming numbers. You know that "53" is "Fifty-three." So "253" is "Two hundred fifty-three." Using the examples above, look at these...

148 - One hundred forty-eight.

273 - Two hundred seventy-three.

510 - Five hundred ten.

888 - Eight hundred eighty-eight.
