Identify Dollar Bills and Use the Dollar Symbol

Today we'll learn how to name dollar bills and write money amounts.

Here's a key idea — one hundred cents is the same as one dollar.

These are the bills we use most: one, five, ten, and twenty dollars.

This is the one-dollar bill — it's worth just one dollar.

This is the five-dollar bill — it's worth five dollars.

This is the ten-dollar bill — it's worth ten dollars.

And this is the twenty-dollar bill — it's worth twenty dollars.

Sam has one ten-dollar bill and one five-dollar bill. How much money does he have?

Ten plus five equals fifteen.

We use the dollar symbol — this curly S — to show it's money. Write a dollar sign, then fifteen.

We can also write it with a decimal point and two zeros for the cents.

Sam has fifteen dollars — written dollar sign one five point zero zero. Nice work!
