3-Digit Addition Summer Color by Number - Beach - Lucky Little ... - Free Printable

I'll solve this color-by-number worksheet by calculating each addition problem and determining the correct color based on the sum.

Let me work through all the problems systematically:

Color Key:
- 201-300 = WHITE

- 153 + 113: 153 + 100 = 253, + 13 = 266 ✓
- 298 + 224: 298 + 200 = 498, + 24 = 522 ✓
- 710 + 156: 710 + 100 = 810, + 56 = 866 ✓
- 522 + 373: 522 + 300 = 822, + 73 = 895 ✓
- 358 + 344: 358 + 300 = 658, + 44 = 702 ✓
- 581 + 280: 581 + 200 = 781, + 80 = 861 ✓

All calculations appear correct.
