Solve addition problems to uncover the hidden picture in this fun math activity.

Let me work through this step by step.

First, I need to solve the addition problems at the top:

Blue box: 6 + 4 = 10
Red box: 2 + 1 = 3
Yellow box: 5 + 2 = 7
Brown box: 8 + 1 = 9
Orange box: 1 + 1 = 2
Green box: 2 + 6 = 8
Light brown box: 3 + 3 = 6
Dark brown box: 4 + 1 = 5
Navy blue box: 2 + 2 = 4

So the answers are:
- Blue = 10
- Red = 3
- Yellow = 7
- Brown = 9
- Orange = 2
- Green = 8
- Light brown = 6
- Dark brown = 5
- Navy blue = 4

Now I need to find these numbers in the grid and color them according to their colors. Looking at the grid, I can see there's already one circle marked (appears to be on a "5" in row 7).

The task is to find all instances of each answer number and color them with the corresponding color from the key.

Let me verify my calculations again:
- 6 + 4 = 10 ✓
- 2 + 1 = 3 ✓
- 5 + 2 = 7 ✓
- 8 + 1 = 9 ✓
- 1 + 1 = 2 ✓
- 2 + 6 = 8 ✓
- 3 + 3 = 6 ✓
- 4 + 1 = 5 ✓
- 2 + 2 = 4 ✓

All calculations are correct.

Final Answer:
Blue (10): Color all 10s in the grid
Red (3): Color all 3s in the grid
Yellow (7): Color all 7s in the grid
Brown (9): Color all 9s in the grid
Orange (2): Color all 2s in the grid
Green (8): Color all 8s in the grid
Light brown (6): Color all 6s in the grid
Dark brown (5): Color all 5s in the grid
Navy blue (4): Color all 4s in the grid
