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.
