Whole numbers in expanded form review
CCSS.Math:
Review writing whole numbers in expanded form, and try some practice problems.
Expanded form
Expanded form is a way to write a number by adding the value of its digits.
We can use a place value chart to think of the value of a number's digits.
Example
Let's write 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 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 expanded form is start color #11accd, 7000, end color #11accd, plus, start color #7854ab, 200, end color #7854ab, plus, start color #1fab54, 20, end color #1fab54, plus, start color #ca337c, 9, end color #ca337c.
