Read and write numbers to 1,000,000 - Master The Curriculum - Free Printable

Problem Analysis:

The task involves several parts related to reading, writing, and manipulating numbers up to 1,000,000. Let's break it down step by step:

---

#### Part 1: Writing Numbers in Words
We need to write the given numbers in words.

1. 54,980
- Breakdown:
- 54,000 = Fifty-four thousand
- 980 = Nine hundred eighty
- Combined: Fifty-four thousand, nine hundred eighty

2. 73,521
- Breakdown:
- 73,000 = Seventy-three thousand
- 521 = Five hundred twenty-one
- Combined: Seventy-three thousand, five hundred twenty-one

3. 89,735
- Breakdown:
- 89,000 = Eighty-nine thousand
- 735 = Seven hundred thirty-five
- Combined: Eighty-nine thousand, seven hundred thirty-five

---

#### Part 2: Writing Numbers from Expanded Form
We need to combine the expanded forms into single numbers.

1. 400,000 + 20,000 + 3,000 + 700 + 40 + 1
- Sum:
\( 400,000 + 20,000 + 3,000 + 700 + 40 + 1 = 423,741 \)
- Answer: 423,741

2. 520,000 + 40,000 + 2,000 + 900 + 30 + 8
- Sum:
\( 520,000 + 40,000 + 2,000 + 900 + 30 + 8 = 562,938 \)
- Answer: 562,938

3. 680,000 + 30,000 + 8,000 + 300 + 90 + 3
- Sum:
\( 680,000 + 30,000 + 8,000 + 300 + 90 + 3 = 718,393 \)
- Answer: 718,393

#### Part 3: Filling in the Number Line
We need to fill in the missing numbers in the number lines based on the given patterns.

1. Number Line 1: 351,207 → ? → ? → ? → ? → 351,212
- The difference between consecutive numbers is consistent.
- Difference: \( 351,212 - 351,207 = 5 \)
- Fill in the gaps:
- \( 351,207 + 5 = 351,212 \)
- \( 351,212 + 5 = 351,217 \)
- \( 351,217 + 5 = 351,222 \)
- \( 351,222 + 5 = 351,227 \)
- Final sequence: 351,207 → 351,212 → 351,217 → 351,222 → 351,227 → 351,232

2. Number Line 2: ? → 820,630 → ? → ? → 820,633 → ?
- The difference between consecutive numbers is consistent.
- Difference: \( 820,633 - 820,630 = 3 \)
- Fill in the gaps:
- \( 820,630 - 3 = 820,627 \)
- \( 820,630 + 3 = 820,633 \)
- \( 820,633 + 3 = 820,636 \)
- Final sequence: 820,627 → 820,630 → 820,633 → 820,636 → 820,639

3. Number Line 3: ? → ? → ? → 934,780 → ? → ?
- The difference between consecutive numbers is consistent.
- Assume the difference is \( d \). Since we only have one known number, we cannot determine \( d \) without additional information. However, if we assume a common pattern (e.g., \( d = 10 \)), we can fill in the gaps:
- \( 934,780 - 10 = 934,770 \)
- \( 934,770 - 10 = 934,760 \)
- \( 934,780 + 10 = 934,790 \)
- \( 934,790 + 10 = 934,800 \)
- Final sequence (assuming \( d = 10 \)): 934,760 → 934,770 → 934,780 → 934,790 → 934,800

Final Answers:

1. Writing Numbers in Words:
- 54,980: Fifty-four thousand, nine hundred eighty
- 73,521: Seventy-three thousand, five hundred twenty-one
- 89,735: Eighty-nine thousand, seven hundred thirty-five

2. Writing Numbers from Expanded Form:
- 400,000 + 20,000 + 3,000 + 700 + 40 + 1: 423,741
- 520,000 + 40,000 + 2,000 + 900 + 30 + 8: 562,938
- 680,000 + 30,000 + 8,000 + 300 + 90 + 3: 718,393

3. Filling in the Number Line:
- Number Line 1: 351,207 → 351,212 → 351,217 → 351,222 → 351,227 → 351,232
- Number Line 2: 820,627 → 820,630 → 820,633 → 820,636 → 820,639
- Number Line 3: 934,760 → 934,770 → 934,780 → 934,790 → 934,800
