Addition color by number worksheet - First grade - Treasure hunt 4 ... - Free Printable

Problem Description:

The task is a "Color by Number" activity where you need to solve addition problems in each cell of the grid. The results of these additions will determine which color to use for that cell based on the provided color key.

Color Key:

- 3: Green
- 4: Red
- 5: Blue
- 6: Orange
- 7: Purple
- 8: Yellow
- 9: Pink

Solution Approach:

1. Identify Each Addition Problem: Each cell in the grid contains an addition problem.
2. Solve the Addition Problems: Calculate the sum of each addition problem.
3. Match the Sum to the Color Key: Use the result of each addition to determine the corresponding color from the color key.
4. Color the Grid: Fill each cell with the appropriate color based on the calculated sum.

Step-by-Step Solution:

#### Top Row:
- Cell 1: \( 3 + 6 = 9 \) → Pink
- Cell 2: \( 3 + 3 = 6 \) → Orange
- Cell 3: \( 5 + 1 + 3 = 9 \) → Pink
- Cell 4: \( 5 + 2 = 7 \) → Purple
- Cell 5: \( 4 + 2 + 3 = 9 \) → Pink
- Cell 6: \( 5 + 3 = 8 \) → Yellow
- Cell 7: \( 9 + 0 = 9 \) → Pink

#### Second Row:
- Cell 1: \( 2 + 2 + 2 + 3 = 9 \) → Pink
- Cell 2: \( 5 + 1 = 6 \) → Orange
- Cell 3: \( 1 + 8 = 9 \) → Pink
- Cell 4: \( 3 + 2 + 2 = 7 \) → Purple
- Cell 5: \( 3 + 4 = 7 \) → Purple
- Cell 6: \( 6 + 3 = 9 \) → Pink
- Cell 7: \( 2 + 2 + 2 = 6 \) → Orange
- Cell 8: \( 4 + 5 = 9 \) → Pink

#### Third Row:
- Cell 1: \( 8 + 1 = 9 \) → Pink
- Cell 2: \( 1 + 3 + 2 = 6 \) → Orange
- Cell 3: \( 2 + 2 - 5 = -1 \) (This seems incorrect; assuming it's a typo, let's ignore or recheck)
- Cell 4: \( 6 + 0 = 6 \) → Orange
- Cell 5: \( 6 + 1 = 7 \) → Purple
- Cell 6: \( 6 + 2 + 1 = 9 \) → Pink
- Cell 7: \( 3 + 2 + 2 = 7 \) → Purple
- Cell 8: \( 3 + 3 + 3 + 6 = 15 \) (This seems incorrect; assuming it's a typo, let's ignore or recheck)
- Cell 9: \( 2 + 7 = 9 \) → Pink

#### Fourth Row:
- Cell 1: \( 9 + 0 = 9 \) → Pink
- Cell 2: \( 2 + 3 = 5 \) → Blue
- Cell 3: \( 1 + 8 = 9 \) → Pink
- Cell 4: \( 1 + 4 = 5 \) → Blue
- Cell 5: \( 5 + 4 = 9 \) → Pink
- Cell 6: \( 7 + 2 = 9 \) → Pink
- Cell 7: \( 3 + 1 = 4 \) → Red
- Cell 8: \( 8 + 1 = 9 \) → Pink
- Cell 9: \( 7 + 2 = 9 \) → Pink
- Cell 10: \( 3 + 0 = 3 \) → Green
- Cell 11: \( 5 + 4 = 9 \) → Pink
- Cell 12: \( 1 + 1 + 1 = 3 \) → Green

#### Fifth Row:
- Cell 1: \( 5 + 4 = 9 \) → Pink
- Cell 2: \( 1 + 2 + 2 = 5 \) → Blue
- Cell 3: \( 5 + 0 = 5 \) → Blue
- Cell 4: \( 7 + 2 = 9 \) → Pink
- Cell 5: \( 3 + 1 = 4 \) → Red
- Cell 6: \( 4 + 0 = 4 \) → Red
- Cell 7: \( 0.9 \) (This seems incorrect; assuming it's a typo, let's ignore or recheck)
- Cell 8: \( 7 + 2 = 9 \) → Pink
- Cell 9: \( 9 + 0 = 9 \) → Pink
- Cell 10: \( 2 + 1 = 3 \) → Green
- Cell 11: \( 2 + 2 + 5 = 9 \) → Pink

#### Sixth Row:
- Cell 1: \( 1 + 1 + 3 = 5 \) → Blue
- Cell 2: \( 0 + 9 = 9 \) → Pink
- Cell 3: \( 3 + 2 = 5 \) → Blue
- Cell 4: \( 8 + 1 = 9 \) → Pink
- Cell 5: \( 6 + 3 = 9 \) → Pink
- Cell 6: \( 1 + 2 + 1 = 4 \) → Red
- Cell 7: \( 1 + 8 = 9 \) → Pink
- Cell 8: \( 2 + 2 + 5 = 9 \) → Pink
