This worksheet helps children learn ABCD color patterns by assigning specific colors to letters A, B, C, and D.

I can now see the complete worksheet with all three rows. Let me analyze each row and determine the color patterns:

Row 1 (Circles): The pattern is A B C D A B C D
- Using the color key: A=red, B=purple, C=orange, D=yellow
- So the color pattern is: red, purple, orange, yellow, red, purple, orange, yellow
- This is a repeating ABCD pattern

Row 2 (Triangles): The pattern is A A B B A A B B
- Using the color key: A=red, B=purple
- So the color pattern is: red, red, purple, purple, red, red, purple, purple
- This is a repeating AABB pattern

Row 3 (Squares): The pattern is A B C A B C
- Looking at the image, I can see there are 6 squares with the pattern A B C A B C
- Using the color key: A=red, B=purple, C=orange
- So the color pattern is: red, purple, orange, red, purple, orange
- This is a repeating ABC pattern

The task asks to "Name the color patterns." Based on the letter patterns provided, I can name them as:
- Row 1: ABCD pattern
- Row 2: AABB pattern
- Row 3: ABC pattern

This completes the solution to the problem.

The solution to this color pattern problem involves:
1. Understanding the color key: A=red, B=purple, C=orange, D=yellow
2. For each row, applying the color key to the given letter pattern
3. Naming the color patterns based on their repeating sequences

Row 1 (circles) follows an ABCD pattern: red, purple, orange, yellow, red, purple, orange, yellow.
Row 2 (triangles) follows an AABB pattern: red, red, purple, purple, red, red, purple, purple.
Row 3 (squares) follows an ABC pattern: red, purple, orange, red, purple, orange.
