Math worksheet for practicing place value and number sense with the number 8,351,207.

Let's solve the problem step by step based on the worksheet titled "Special Number" with the number 8,351,207.

Step 1: Identify the special number

The special number is:
8,351,207

---

Step 2: Determine if the number is even or odd

- A number is even if its last digit is even (0, 2, 4, 6, 8).
- A number is odd if its last digit is odd (1, 3, 5, 7, 9).

The last digit of 8,351,207 is 7, which is odd.

✔ So, the answer is: odd

---

Step 3: Value of each digit

We'll determine the place value of each digit in 8,351,207:

Break down the number by place values:
```
8,351,207
= 8,000,000 + 300,000 + 50,000 + 1,000 + 200 + 0 + 7
```

Now, answer each question:

- The value of the digit 5 is:
→ The 5 is in the ten thousands place → 50,000

- The value of the digit 7 is:
→ The 7 is in the ones place → 7

- The value of the digit 3 is:
→ The 3 is in the hundred thousands place → 300,000

- The value of the digit 2 is:
→ The 2 is in the hundreds place → 200

- The value of the digit 8 is:
→ The 8 is in the millions place → 8,000,000

Step 4: Fill in the empty boxes on the number line

We are given a number line with:
- A point at 8,351,207
- A point at 8,351,210
- We need to fill in the missing numbers.

Since 8,351,210 is 3 more than 8,351,207, we can assume the number line increases by 1 each step.

So, the sequence should be:

→ ... → 8,351,205 → 8,351,206 → 8,351,207 → 8,351,208 → 8,351,209 → 8,351,210 → ...

So, the missing boxes (assuming two before and two after):

- Before 8,351,207:
- First box: 8,351,205
- Second box: 8,351,206

- After 8,351,207:
- Third box: 8,351,208
- Fourth box: 8,351,209

✔ So, the number line becomes:
```
[8,351,205] → [8,351,206] → [8,351,207] → [8,351,208] → [8,351,209] → [8,351,210]
```

Step 5: Write the number in expanded form

Expanded form means writing the number as the sum of its place values.

8,351,207 = 8,000,000 + 300,000 + 50,000 + 1,000 + 200 + 0 + 7

But since the blank is likely for the non-zero digits:

✔ So:
8,000,000 + 300,000 + 50,000 + 1,000 + 200 + 7

(We skip the 0 in tens place.)

---

Step 6: Add or subtract from the number

- 1,000,000 less than 8,351,207
→ 8,351,207 − 1,000,000 = 7,351,207

- 1,000 more than 8,351,207
→ 8,351,207 + 1,000 = 8,352,207

- 100,000 less than 8,351,207
→ 8,351,207 − 100,000 = 8,251,207

- 10 more than 8,351,207
→ 8,351,207 + 10 = 8,351,217

- 1 less than 8,351,207
→ 8,351,207 − 1 = 8,351,206

---

Step 7: Compare the numbers using <, >, or =

Compare each pair:

1. 8,513,207 vs 8,351,207
→ 8,513,207 > 8,351,207 → ✔ >

2. 8,251,307 vs 8,351,207
→ 8,251,307 < 8,351,207 → ✔ <

3. 8,351,207 vs 8,315,207
→ 8,351,207 > 8,315,207 → ✔ >

4. 8,351,207 vs 8,351,702
→ Compare digit by digit:
- Millions: same (8)
- Hundred thousands: same (3)
- Ten thousands: same (5)
- Thousands: same (1)
- Hundreds: 2 vs 7 → 2 < 7
→ So, 8,351,207 < 8,351,702 → ✔ <
