A. Match the following numbers with their expanded form.

Column A
1. 280
2. 309
3. 488
4. 734
5. 893
6. 969
7. 543

Column B
300 + 00 + 9
700 + 30 + 4
400 + 80 + 8
500 + 40 + 3
900 + 60 + 9
800 + 90 + 3
200 + 80 + 0

B. Write the following numbers in expanded form.
527 = 500 + 20 + 7

Let's work through matching the numbers from Column A with their expanded forms in Column B and then rewrite a given number in expanded form.
A. Matching Numbers with Expanded Form

280 - Expanded form: 200 + 80 + 0

309 - Expanded form: 300 + 0 + 9

488 - Expanded form: 400 + 80 + 8

734 - Expanded form: 700 + 30 + 4

893 - Expanded form: 800 + 90 + 3

969 - Expanded form: 900 + 60 + 9

543 - Expanded form: 500 + 40 + 3


B. Writing Numbers in Expanded Form
The number given is 527:

Hundreds place: 5 × 100 = 500
Tens place: 2 × 10 = 20
Ones place: 7 × 1 = 7

Thus, 527 in expanded form is 500 + 20 + 7 .
Understanding expanded form is important because it helps to recognize the value of each digit in a number according to its position. This concept is a foundational math skill often taught in middle school.
