Adding and Subtracting Integers Codebreaker Worksheet Activity Fun and No-Prep! - Free Printable

Problem Overview:

The task involves solving a "Codebreaker" activity where you use the key on the left to determine which numbers correspond to the images in each row. Once you identify the numbers, you perform addition and subtraction operations as indicated by the symbols (+ or -) between the images.

Key Observations:

1. Key on the Left: Each image is associated with a specific number.
2. Operations: The symbols between the images indicate whether to add (+) or subtract (-).
3. Goal: Solve each equation and find the result for each row.

Step-by-Step Solution:

#### Step 1: Understand the Key
The key on the left assigns numbers to the images:
- 🍔 (Hamburger) = 4
- 🥪 (Sandwich) = 3
- 🌮 (Taco) = -5
- 🥤 (Smoothie) = 8
- 🥗 (Salad) = -2
- 🥫 (Bottle) = 1
- 🥤 (Milkshake) = -3
- 🍦 (Ice Cream) = -7

#### Step 2: Solve Each Row

##### Row 1:
- Image 1: 🍔 + 🥪
- Numbers: 4 + 3 = 7
- Image 2: 🥪 + 🥤
- Numbers: 3 + 8 = 11

##### Row 2:
- Image 1: 🌮 + 🥪
- Numbers: -5 + 3 = -2
- Image 2: 🥪 + 🥪
- Numbers: 3 + 3 = 6

##### Row 3:
- Image 1: 🥤 + 🥫
- Numbers: 8 + 1 = 9
- Image 2: 🥫 + 🥫
- Numbers: 1 + 1 = 2

##### Row 4:
- Image 1: 🥬 - 🥫
- Numbers: -2 - 1 = -3
- Image 2: 🥫 - 🥫
- Numbers: 1 - 1 = 0

##### Row 5:
- Image 1: 🍔 - 🥤
- Numbers: 4 - 8 = -4
- Image 2: 🥤 - 🥤
- Numbers: 8 - 8 = 0

##### Row 6:
- Image 1: 🥫 - 🥬
- Numbers: 1 - (-2) = 1 + 2 = 3
- Image 2: 🥬 - 🥫
- Numbers: -2 - 1 = -3

##### Row 7:
- Image 1: 🍔 - 🥫
- Numbers: 4 - 1 = 3
- Image 2: 🥫 - 🥫
- Numbers: 1 - 1 = 0

##### Row 8:
- Image 1: 🥤 - 🥫
- Numbers: 8 - 1 = 7
- Image 2: 🥫 - 🥤
- Numbers: 1 - 8 = -7

#### Final Results:
Here are the solutions for each row:

| Row | Image 1 | Result | Image 2 | Result |
|-----|---------------|--------|---------------|--------|
| 1 | 🍔 + 🥪 | 7 | 🥪 + 🥤 | 11 |
| 2 | 🌮 + 🥪 | -2 | 🥪 + 🥪 | 6 |
| 3 | 🥤 + 🥫 | 9 | 🥫 + 🥫 | 2 |
| 4 | 🥬 - 🥫 | -3 | 🥫 - 🥫 | 0 |
| 5 | 🍔 - 🥤 | -4 | 🥤 - 🥤 | 0 |
| 6 | 🥫 - 🥬 | 3 | 🥬 - 🥫 | -3 |
| 7 | 🍔 - 🥫 | 3 | 🥫 - 🥫 | 0 |
| 8 | 🥤 - 🥫 | 7 | 🥫 - 🥤 | -7 |

Final Answer:

$$
\boxed{
\begin{array}{c|c|c}
\text{Row} & \text{Image 1 Result} & \text{Image 2 Result} \\
\hline
1 & 7 & 11 \\
2 & -2 & 6 \\
3 & 9 & 2 \\
4 & -3 & 0 \\
5 & -4 & 0 \\
6 & 3 & -3 \\
7 & 3 & 0 \\
8 & 7 & -7 \\
\end{array}
}
