CCSS.Math:

Review writing whole numbers in written form, and try some practice problems.

## Written form

**Written form**is a way to write numbers using only words.

### Example

Let's write start color #11accd, 7, end color #11accd, comma, start color #7854ab, 2, end color #7854ab, start color #1fab54, 2, end color #1fab54, start color #ca337c, 9, end color #ca337c in expanded form.

Thousands | Hundreds | Tens | Ones |
---|---|---|---|

start color #11accd, 7, end color #11accd | start color #7854ab, 2, end color #7854ab | start color #1fab54, 2, end color #1fab54 | start color #ca337c, 9, end color #ca337c |

7229, equals, start color #11accd, 7, end color #11accd, start text, space, t, h, o, u, s, a, n, d, s, end text plus, start color #7854ab, 2, end color #7854ab, start text, space, h, u, n, d, r, e, d, s, end text, plus start color #1fab54, 2, end color #1fab54, start text, space, t, e, n, s, end text, plus, start color #ca337c, 9, end color #ca337c, start text, space, o, n, e, s, end text

7229 in written form is start text, start color #11accd, s, e, v, e, n, space, t, h, o, u, s, a, n, d, end color #11accd, comma, start color #7854ab, space, t, w, o, space, h, u, n, d, r, e, d, end color #7854ab, start color #1fab54, space, t, w, e, n, t, y, negative, end color #1fab54, start color #ca337c, n, i, n, e, end color #ca337c, end text

- why do we have to practice(9 votes)
- It isn't practical to write out large numbers in words most of the time. It's more of understanding how all numbers can be written as their digits multiplied by their respective power of 10. If you ever write a check though, you will need to write the amount of money in words.(6 votes)

- Is there an easier way to write written form? it is a bit tiring when you write it.(8 votes)
- Unfortunately not. Written form is the more "expanded" version of standard form, so I suppose instead of writing out "nine hundred sixty-seven" you could just simplify it to 967.

Generally, written form is the kind of thing you learn once and then never use again. It's just useful for learning to speak numbers.(7 votes)
