Fun and educational multiplication activity for kids with a colorful monster theme.

To solve this color-by-multiplication worksheet, we need to calculate the answer for each multiplication problem inside the sections of the picture. Then, we match that answer to the color key at the top.

Here is the step-by-step breakdown for each number:

Color Key:
* 6 = Light Yellow
* 7 = Orange
* 8 = Dark Yellow
* 9 = Purple
* 10 = Dark Red
* 11 = Black
* 12 = Light Red

Calculations by Section:

Top Row (Background & Horns):
* $2 \times 3 = 6$ (Light Yellow)

* $6 \times 1 = 6$ (Light Yellow)
* $1 \times 12 = 12$ (Light Red)
* $3 \times 2 = 6$ (Light Yellow)

Second Row (Horns & Face):
* $1 \times 11 = 11$ (Black)
* $2 \times 5 = 10$ (Dark Red)
* $11 \times 1 = 11$ (Black)
* $6 \times 2 = 12$ (Light Red)
* $3 \times 4 = 12$ (Light Red)
* $7 \times 1 = 7$ (Orange)

Third Row (Eyes & Cheeks):
* $10 \times 1 = 10$ (Dark Red)
* $1 \times 10 = 10$ (Dark Red)
* $1 \times 6 = 6$ (Light Yellow)
* $2 \times 5 = 10$ (Dark Red)
* $5 \times 2 = 10$ (Dark Red)
* $6 \times 1 = 6$ (Light Yellow)
* $2 \times 6 = 12$ (Light Red)

Fourth Row (Body & Arms):
* $4 \times 3 = 12$ (Light Red)
* $3 \times 3 = 9$ (Purple)
* $5 \times 2 = 10$ (Dark Red)
* $1 \times 10 = 10$ (Dark Red)
* $1 \times 9 = 9$ (Purple)
* $2 \times 3 = 6$ (Light Yellow)

Fifth Row (Belly & Legs):
* $7 \times 1 = 7$ (Orange)
* $3 \times 3 = 9$ (Purple)
* $1 \times 9 = 9$ (Purple)
* $2 \times 5 = 10$ (Dark Red)
* $1 \times 7 = 7$ (Orange)
* $4 \times 3 = 12$ (Light Red)

Sixth Row (Feet & Lower Body):
* $12 \times 1 = 12$ (Light Red)
* $2 \times 6 = 12$ (Light Red)
* $10 \times 1 = 10$ (Dark Red)
* $3 \times 3 = 9$ (Purple)
* $1 \times 6 = 6$ (Light Yellow)
* $3 \times 4 = 12$ (Light Red)

Bottom Row (Feet):
* $2 \times 3 = 6$ (Light Yellow)
* $1 \times 7 = 7$ (Orange)
* $3 \times 3 = 9$ (Purple)
* $1 \times 6 = 6$ (Light Yellow)
* $9 \times 1 = 9$ (Purple)
* $7 \times 1 = 7$ (Orange)
* $4 \times 3 = 12$ (Light Red)
* $3 \times 2 = 6$ (Light Yellow)
* $12 \times 1 = 12$ (Light Red)

Final Answer:
To complete the picture, color the sections according to these answers:
- 6 (Light Yellow): $2 \times 3$, $1 \times 7$, $6 \times 1$, $3 \times 2$, $1 \times 6$, $6 \times 1$, $2 \times 3$, $2 \times 3$, $1 \times 6$, $3 \times 2$.
- 7 (Orange): $1 \times 7$, $7 \times 1$, $7 \times 1$, $1 \times 7$, $7 \times 1$.
- 8 (Dark Yellow): No sections equal 8.
- 9 (Purple): $3 \times 3$, $1 \times 9$, $3 \times 3$, $1 \times 9$, $3 \times 3$, $9 \times 1$.
- 10 (Dark Red): $2 \times 5$, $10 \times 1$, $1 \times 10$, $2 \times 5$, $5 \times 2$, $5 \times 2$, $1 \times 10$, $2 \times 5$, $10 \times 1$.
- 11 (Black): $1 \times 11$, $11 \times 1$.
- 12 (Light Red): $1 \times 12$, $3 \times 2$, $6 \times 2$, $3 \times 4$, $6 \times 1$, $2 \times 6$, $4 \times 3$, $12 \times 1$, $2 \times 6$, $3 \times 4$, $4 \times 3$, $12 \times 1$.
