Students can practice their counting and color recognition by filling in the 100 dots within this "100 Days" design.

Problem Description:

The task involves coloring 100 dots on a page according to specific instructions. The instructions are as follows:

- Color 10 dots in red.
- Color 20 dots in blue.
- Color 30 dots in green.
- Color 10 dots in orange.
- Color 20 dots in yellow.
- Color 30 dots in purple.

The goal is to ensure that all 100 dots are colored correctly according to the given distribution of colors.

Solution Approach:

1. Verify the Total Number of Dots:
- The instructions specify coloring 100 dots in total.
- Let's sum up the number of dots for each color:
\[
10 (\text{red}) + 20 (\text{blue}) + 30 (\text{green}) + 10 (\text{orange}) + 20 (\text{yellow}) + 30 (\text{purple}) = 100
\]
- The total matches the requirement of 100 dots.

2. Color Distribution:
- Red: 10 dots
- Blue: 20 dots
- Green: 30 dots
- Orange: 10 dots
- Yellow: 20 dots
- Purple: 30 dots

3. Implementation Steps:
- Carefully count and select 10 dots to color red.
- Select another 20 dots to color blue.
- Continue this process for green (30 dots), orange (10 dots), yellow (20 dots), and purple (30 dots).
- Ensure no dot is colored more than once and that all 100 dots are used.

4. Verification:
- After coloring, double-check that:
- Exactly 10 dots are red.
- Exactly 20 dots are blue.
- Exactly 30 dots are green.
- Exactly 10 dots are orange.
- Exactly 20 dots are yellow.
- Exactly 30 dots are purple.
- Confirm that no dots are left uncolored and no dots are colored incorrectly.
