The worksheet you provided is focused on estimating the products of greater numbers, using compatible numbers for easier mental multiplication.

Here is a breakdown of the instructions and some examples of how the problems are approached:

### Instructions (Based on what I can see):
1. **Step 1**: Choose compatible numbers that are close to the actual numbers.
2. **Step 2**: Multiply these compatible numbers for an estimated product.

#### Example from the sheet:
- **Problem**: A roller coaster has 38 seats and runs 24 times each hour. How many passengers can ride per hour?
   - 24 is close to 25, and 38 is close to 40.
   - Estimation: \( 25 \times 40 = 1,000 \)
   - About 1,000 passengers can ride each hour.

#### Levelled Practice (Estimations for 1-16):
Here are a few examples based on the estimation strategy:

1. **23 × 12**:
   - Estimate: \( 25 \times 10 = 250 \)

2. **24 × 31**:
   - Estimate: \( 25 \times 30 = 750 \)

3. **19 × 24**:
   - Estimate: \( 20 \times 25 = 500 \)

4. **51 × 17**:
   - Estimate: \( 50 \times 20 = 1,000 \)

5. **82 × 78**:
   - Estimate: \( 80 \times 80 = 6,400 \)

### 5 Relative Questions:
1. How can we refine estimates when numbers are farther from round values?
2. How does estimating with compatible numbers help in real-life scenarios?
3. What are the advantages of mental math for estimation?
4. How would you adjust your estimate if both numbers were closer to 50?
5. What strategies can be used when estimating the product of decimals?

**Tip**: Estimating products can help check the reasonableness of exact answers when calculating manually or with a calculator.
