**I. How to Remember the Place Value Positions**

As always…look for patterns.

Numbers are infinite, but let’s look at the place values through the billions.

-------------- ------- -------------- ---------, ------------------- --------------- ---------, ------------------------ ---------------- -------------, ---------- ------- --------

Hundred Billions Tens Billions Billions, Hundred Millions Ten Millions Millions, Hundred Thousands, Ten Thousands, Thousand, Hundreds, Tens, Ones

Notice, starting from the right we have the familiar

**units**ones, tens and hundreds

Thereafter, every three places have a name in common and are

**separated by a comma.**

Let’s call them groups. There are three other groups above.

**B**illions – red

**M**illions – blue

**T**housands – green

Think of a word that begins with the first letter of each group to help you remember the order of the groups and units.

It can be silly. For example

**B**illions –

**B**everly

**M**illions –

**M**ackie

**T**housands –

**T**ickles

**H**undreds –

**H**airy

**T**ens -

**T**an

**O**nes -

**O**ctopuses.

Now, look at the names of the billions, millions, and thousands and what else do you see in common? Each group starting from right to left has the base name for the group followed by ten and then a hundred. Then, a new group starts over with the same pattern. Take another look. Once these patterns are realized, it becomes easier to remember the order.

**II. How to Read Whole Numbers**

432 –is read as four hundred thirty-two

432 –

Notice, I did not say four hundred

**and**thirty-two. The word “and” is reserved for the decimal point.

Since each group is divided into three places, read larger numbers as if they were units then say the group name. You can also think of groups as families.

**For example: 567, 193**

Read from left to right. Say five hundred sixty-seven; okay; stop; based upon the positions, what group is 567 in? Yes, the

**thousands**; therefore the number is read as five hundred sixty-seven thousand, one hundred ninety-three

**II. How to Write Whole Numbers in Words**

Numbers are written as they are read. Just remember to separate the groups with commas and don’t use the word “and.” Look at the number above for an example. Here’s another example:

439,023,456 – four hundred thirty-nine million

**,**twenty-three thousand

**,**four hundred fifty-six
