Estimation Nearest Thousand worksheet with 12 subtraction problems.

It looks like you've uploaded an image of a worksheet titled "Estimation: Nearest Thousand", which asks students to estimate the sum or difference of two numbers by rounding each number to the nearest thousand, and then perform the operation.

Since I can't view images directly, I'll guide you on how to solve such problems step-by-step. If you provide the actual numbers from the worksheet (e.g., "1. 45,890 → ___ + 32,108 → ___"), I can help solve them.

But here’s how to approach this type of problem:

🔧 Step-by-Step Guide: Estimating to the Nearest Thousand

#### Step 1: Round Each Number to the Nearest Thousand
To round a number to the nearest thousand:
- Look at the hundreds digit.
- If it's 5 or more, round up.
- If it's less than 5, round down.

For example:
- 45,890 → hundreds digit is 8 → round up → 46,000
- 32,108 → hundreds digit is 1 → round down → 32,000

#### Step 2: Add or Subtract the Rounded Numbers
Now perform the operation with the rounded numbers.

Example:
- 45,890 + 32,108 ≈ 46,000 + 32,000 = 78,000

✔ Example Problem Solved

Let’s assume one of the problems is:

> 1. 45,890 → ___ + 32,108 → ___

Solution:
- 45,890 → round to nearest thousand: 46,000
- 32,108 → round to nearest thousand: 32,000
- Estimated sum: 46,000 + 32,000 = 78,000

So, fill in:
- 45,890 → 46,000
- 32,108 → 32,000
- Sum: 78,000

If you list the problems from the worksheet (like the numbers in each row), I can solve all of them for you.

Just paste the numbers like:

```
1. 45,890 → ___ + 32,108 → ___
2. 55,405 → ___ - 38,720 → ___
...
```

And I’ll complete the estimation for each!
