Writing Numbers 3 - Mayan Numbers
The ancient Mayan people wrote their numbers
different than we do today. They wrote their
numbers with shells, dots and lines.
For example, this number is five:
How much is 5 + 5 ? ________
So this number is ten, because it has two
fives.
Why is this number fifteen?
This number is eight. Why is this number eight?

Writing Numbers 7 - Write That Dash
There is a trick to writing numbers 21 to 99. Every single one of those numbers
has a dash - in it. Here are some examples:
21 twenty-one 63 sixty-three
44 forty-four 37 thirty-seven
See how each number has a dash in it? If you forget the dash, the number iswrong... so don't forget!
Write each number... and remember to use a dash.

Writing Numbers 10 - No "And"
When you write a number, such as 194, do NOT write the word "and". When you
are talking about numbers, the word "and" means a decimal point.
One hundred ninety-four looks like this: 194
One hundred and ninety-four looks like this: 100.94
We are not going to be writing decimal points today, so do not write the word "and"
in your numbers.

Writing Numbers 17 - Hundred Thousands
Look at this number: 321,000. Notice the 321 at the beginning of the number.
Because all those numbers are in the thousand's place and the ten thousand's place
and the hundred thousand's place, when we read it we read it as three hundred
twenty-one thousand.
If the number were 321,492, we would read it as:
three hundred twenty-one thousand, four hundred ninety-two
Write the numbers. Remember NOT to write the word "and". Also, remember
that a comma goes in between the number in the thousand's place and the
hundred's place.
