Solve the addition problems and color the butterfly using the provided color key.

I'll solve this butterfly color-by-numbers worksheet step by step.

First, let me understand the color code:
- 2 = brown
- 3 = pink
- 4 = purple
- 5 = gray
- 6 = green
- 7 = yellow
- 8 = orange
- 9 = red
- 10 = light blue
- 11 = dark blue

Now I need to solve all the addition problems in each section and determine what color each section should be.

Let me work through the problems systematically:

Left wing (top to bottom):
- 3+4 = 7 → yellow
- 6+4 = 10 → light blue
- 0+6 = 6 → green
- 1+9 = 10 → light blue
- 1+2+3 = 6 → green
- 2+4 = 6 → green
- 0+2 = 2 → brown
- 3+3 = 6 → green
- 1+1 = 2 → brown
- 2+3 = 5 → gray
- 1+1 = 2 → brown
- 5+0 = 5 → gray
- 0+2 = 2 → brown
- 5+2 = 7 → yellow
- 2+0 = 2 → brown
- 3+4 = 7 → yellow

Center body area:
- 9+1 = 10 → light blue
- 5+5 = 10 → light blue
- 2+8 = 10 → light blue
- 4+6 = 10 → light blue
- 3+7 = 10 → light blue
- 1+4 = 5 → gray
- 2+0 = 2 → brown
- 4+2 = 6 → green
- 1+5 = 6 → green

Right wing (top to bottom):
- 3+7 = 10 → light blue
- 5+3 = 8 → orange
- 1+7 = 8 → orange
- 1+2 = 3 → pink
- 3+0 = 3 → pink
- 5+2 = 7 → yellow
- 7+3 = 10 → light blue
- 5+5 = 10 → light blue
- 1+5 = 6 → green
- 7+2 = 9 → red
- 6+5 = 11 → dark blue
- 2+7 = 9 → red
- 6+1 = 7 → yellow
- 2+4 = 6 → green

Top right area:
- 5+5 = 10 → light blue
- 2+8 = 10 → light blue
- 8+0 = 8 → orange
- 0+3 = 3 → pink
- 6+5 = 11 → dark blue
- 2+1 = 3 → pink
- 3+4 = 7 → yellow
- 4+4 = 8 → orange
- 5+4 = 9 → red
- 1+2+1+1+1 = 6 → green
- 3+5 = 8 → orange
- 9+0 = 9 → red
- 6+2 = 8 → orange
- 8+0 = 8 → orange
- 3+1 = 4 → purple
- 0+4 = 4 → purple
- 6+4 = 10 → light blue
- 2+2 = 4 → purple
- 1+1 = 2 → brown
- 2+0 = 2 → brown
- 2+4 = 6 → green

Far right edge:
- 6+4 = 10 → light blue
- 6+2 = 8 → orange
- 5+2 = 7 → yellow
- 8+2 = 10 → light blue
- 2+3+4 = 9 → red
- 3+2+3 = 8 → orange
- 1+6 = 7 → yellow
- 3+3 = 6 → green
- 8+3 = 11 → dark blue
- 4+0 = 4 → purple
- 9+1 = 10 → light blue
- 2+4 = 6 → green
- 3+0 = 3 → pink
- 4+0 = 4 → purple
- 2+1 = 3 → pink
- 0+3 = 3 → pink
- 1+1 = 2 → brown
- 2+0+2 = 4 → purple
- 1+5 = 6 → green

Bottom center circles:
- 6+3 = 9 → red
- 5+4 = 9 → red
- 6+4 = 10 → light blue
- 1+3 = 4 → purple
- 3+3 = 6 → green

Let me double-check some of the calculations to make sure they're correct...

Actually, I realize I should verify my work more carefully. Let me recalculate a few key ones:

Looking at the butterfly pattern, after solving all the math problems, the student would color each section according to the answers. The final result would show a colorful butterfly with different colored sections based on the sum in each area.

The completed worksheet would have various colors including:
- Light blue (10) appearing frequently
- Green (6) in several areas
- Orange (8) in multiple spots
- Yellow (7) scattered throughout
- Brown (2) in some sections
- Pink (3) in certain areas
- Red (9) in a few places
- Purple (4) in some spots
- Gray (5) in limited areas
- Dark blue (11) in just a couple places

Final Answer:
To complete this worksheet, solve each addition problem and color the corresponding section using the color key provided. For example: 3+4=7 means color that section yellow, 6+4=10 means color it light blue, and so on. Work through all the math problems systematically from top to bottom, left to right, filling in each section with its appropriate color based on your answer.
