Expanded form: Writing a number as the sum of each digit multiplied by its place value.
- Identify the place value of each digit in the number
- Multiply each digit by its place value
- Write all products as an addition expression
3 is in thousands place = 3 × 1,000 = 3,000
4 is in hundreds place = 4 × 100 = 400
8 is in tens place = 8 × 10 = 80
2 is in ones place = 2 × 1 = 2
3,482 = 3,000 + 400 + 80 + 2
3,000 + 400 + 80 + 2 = 3,482 ✓
3,482 = 3,000 + 400 + 80 + 2
• Place value identification: Each digit's position determines its value
• Digit multiplication: Multiply each digit by its place value
• Sum formation: Add all products to form expanded expression
Zero handling: In expanded form, zeros contribute zero value but maintain place value structure.
5 is in thousands place = 5 × 1,000 = 5,000
0 is in hundreds place = 0 × 100 = 0
7 is in tens place = 7 × 10 = 70
0 is in ones place = 0 × 1 = 0
5,070 = 5,000 + 0 + 70 + 0
5,070 = 5,000 + 70
5,000 + 70 = 5,070 ✓
5,070 = 5,000 + 70
• Zero rule: Zeros in expanded form can be omitted since they contribute no value
• Place holder: Zeros maintain the position of non-zero digits
• Simplification: Only non-zero values need to be shown in final answer
Standard form: The regular way of writing a number using digits (e.g., 8,357).
8,000 represents 8 in the thousands place
300 represents 3 in the hundreds place
50 represents 5 in the tens place
7 represents 7 in the ones place
Put the digits in their respective positions: 8,357
8,357 expanded = 8,000 + 300 + 50 + 7 ✓
Standard form: 8,357
• Place value assembly: Each value corresponds to a specific place
• Position matching: Thousands, hundreds, tens, ones
• Verification: Convert back to expanded form to check accuracy

Word problems: Real-world applications of mathematical concepts requiring number interpretation.
4 is in thousands place = 4 × 1,000 = 4,000 (4 groups of 1,000 pages)
0 is in hundreds place = 0 × 100 = 0 (0 groups of 100 pages)
6 is in tens place = 6 × 10 = 60 (6 groups of 10 pages)
3 is in ones place = 3 × 1 = 3 (3 individual pages)
4,063 = 4,000 + 0 + 60 + 3 = 4,000 + 60 + 3
The book has 4,000 pages in thousands groups, 60 pages in tens groups, and 3 individual pages.
4,063 = 4,000 + 60 + 3
Meaning: 4 thousands, 0 hundreds, 6 tens, 3 ones
• Real-world context: Connect abstract numbers to concrete situations
• Place value interpretation: Explain what each value represents
• Zero handling: Understand that zeros maintain place value structure
Mixed format problems: Questions requiring multiple conversions between different number representations.
(9×1,000) = 9,000
(0×100) = 0
(5×10) = 50
(2×1) = 2
9,000 + 0 + 50 + 2 = 9,052
9,052 = Nine thousand fifty-two
Nine thousand fifty-two = 9,052 ✓
Standard form: 9,052
Word form: Nine thousand fifty-two
