3-Digit Addition Coloring Worksheet with Sun Theme

This is a "color by number" worksheet for practicing 3-digit addition. The goal is to solve each addition problem, find the sum, and then color the corresponding section of the sun according to the provided color key.

I will solve this by:
1. Identifying all the 3-digit addition problems in the image.
2. Calculating the sum for each problem.
3. Matching each sum to its correct color range from the key at the bottom.
4. Providing a complete list of problems with their sums and the colors they should be colored.

Let's begin by solving the problems one by one.

Step 1: List all Addition Problems

I can see numerous 3-digit addition problems scattered across the sun's face and rays. I'll start from the top left and work my way around.

- Top Left: `115 + 147`
- Top Center: `131 + 182`
- Top Right: `155 + 154`, `214 + 393`, `226 + 529`
- Middle Left: `286 + 219`, `218 + 174`
- Middle Center: `197 + 371`, `233 + 318`, `225 + 555`, `317 + 134`, `327 + 133`
- Middle Right: `279 + 202`, `196 + 174`, `128 + 332`, `571 + 194`, `195 + 112`, `26? + 36?` (partially obscured)
- Bottom Left: `14? + 15?` (partially obscured), `34? + 377`, `257 + 259`
- Bottom Center: `865 + 107`, `649 + 234`, `313 + 296`, `288 + 279`
- Bottom Right: `131 + 149`, `233 + 127`, `129 + 591`, `546 + 173`, `324 + 228`

Step 2: Calculate the Sums

Now, let's calculate the sum for each of these problems.

- `115 + 147 = 262`
- `131 + 182 = 313`
- `155 + 154 = 309`
- `214 + 393 = 607`
- `226 + 529 = 755`
- `286 + 219 = 505`
- `218 + 174 = 392`
- `197 + 371 = 568`
- `233 + 318 = 551`
- `225 + 555 = 780`
- `317 + 134 = 451`
- `327 + 133 = 460`
- `279 + 202 = 481`
- `196 + 174 = 370`
- `128 + 332 = 460`
- `571 + 194 = 765`
- `195 + 112 = 307`
- `865 + 107 = 972`
- `649 + 234 = 883`
- `313 + 296 = 609`
- `288 + 279 = 567`
- `131 + 149 = 280`
- `233 + 127 = 360`
- `129 + 591 = 720`
- `546 + 173 = 719`
- `324 + 228 = 552`

For the partially obscured problems:
- `14? + 15?`: This appears to be `142 + 154` (based on the visible digits and common worksheet patterns). `142 + 154 = 296`.
- `34? + 377`: This appears to be `342 + 377`. `342 + 377 = 719`.
- `26? + 36?`: This appears to be `263 + 362`. `263 + 362 = 625`.

Step 3: Match Sums to Color Key

The color key at the bottom provides ranges for each color:

- Dark Blue: 230 - 350
- Light Blue: 351 - 425
- Black: 426 - 500
- Dark Green: 501 - 575
- Orange: 576 - 650
- Pink: 651 - 750
- Yellow: 751 - 850
- Tan: 851 - 999

Now, let's assign a color to each problem based on its sum.

- `115 + 147 = 262` → Dark Blue
- `131 + 182 = 313` → Dark Blue
- `155 + 154 = 309` → Dark Blue
- `214 + 393 = 607` → Orange
- `226 + 529 = 755` → Yellow
- `286 + 219 = 505` → Dark Green
- `218 + 174 = 392` → Light Blue
- `197 + 371 = 568` → Dark Green
- `233 + 318 = 551` → Dark Green
- `225 + 555 = 780` → Yellow
- `317 + 134 = 451` → Black
- `327 + 133 = 460` → Black
- `279 + 202 = 481` → Black
- `196 + 174 = 370` → Light Blue
- `128 + 332 = 460` → Black
- `571 + 194 = 765` → Yellow
- `195 + 112 = 307` → Dark Blue
- `865 + 107 = 972` → Tan
- `649 + 234 = 883` → Tan
- `313 + 296 = 609` → Orange
- `288 + 279 = 567` → Dark Green
- `131 + 149 = 280` → Dark Blue
- `233 + 127 = 360` → Light Blue
- `129 + 591 = 720` → Pink
- `546 + 173 = 719` → Pink
- `324 + 228 = 552` → Dark Green
- `142 + 154 = 296` → Dark Blue
- `342 + 377 = 719` → Pink
- `263 + 362 = 625` → Orange
