The task involves spinning a two-digit number from the left wheel and a one-digit number from the right wheel, then adding them together. Below is a step-by-step explanation of how to solve this problem.

---

Step 1: Understand the Wheels


- Left Wheel (Two-Digit Numbers): Contains numbers like 24, 53, 55, 96, 49, 62, 81, 17.
- Right Wheel (One-Digit Numbers): Contains numbers like 4, 5, 6, 2, 3, 9, 1, 6.

You will spin each wheel to select one number from each and then add them together.

---

Step 2: Spin the Wheels and Add


Since the problem does not specify exact spins, we will assume random spins for demonstration purposes. Let's simulate a few spins and calculate the sums.

#### Example Spins:
1. Spin 1:
- Left Wheel: 24
- Right Wheel: 5
- Sum: \( 24 + 5 = 29 \)

2. Spin 2:
- Left Wheel: 53
- Right Wheel: 6
- Sum: \( 53 + 6 = 59 \)

3. Spin 3:
- Left Wheel: 96
- Right Wheel: 3
- Sum: \( 96 + 3 = 99 \)

4. Spin 4:
- Left Wheel: 49
- Right Wheel: 9
- Sum: \( 49 + 9 = 58 \)

5. Spin 5:
- Left Wheel: 62
- Right Wheel: 1
- Sum: \( 62 + 1 = 63 \)

6. Spin 6:
- Left Wheel: 81
- Right Wheel: 6
- Sum: \( 81 + 6 = 87 \)

7. Spin 7:
- Left Wheel: 17
- Right Wheel: 4
- Sum: \( 17 + 4 = 21 \)

8. Spin 8:
- Left Wheel: 55
- Right Wheel: 2
- Sum: \( 55 + 2 = 57 \)

---

Step 3: Write Down the Results


Using the above spins as an example, the completed worksheet would look like this:

```
Adding 2-Digit and 1-Digit Numbers

____ + ____ = ____
24 + 5 = 29
53 + 6 = 59
96 + 3 = 99
49 + 9 = 58
62 + 1 = 63
81 + 6 = 87
17 + 4 = 21
55 + 2 = 57
```

---

Final Answer


If you were to fill in the worksheet based on the spins above, the answers would be:

\[
\boxed{
\begin{aligned}
24 + 5 &= 29 \\
53 + 6 &= 59 \\
96 + 3 &= 99 \\
49 + 9 &= 58 \\
62 + 1 &= 63 \\
81 + 6 &= 87 \\
17 + 4 &= 21 \\
55 + 2 &= 57
\end{aligned}
}
\]
