Color the pattern worksheet featuring geometric shapes with a color key.

To solve this problem, we need to color each shape in the picture according to the key provided at the top.

Step 1: Understand the Color Key
Look at the instructions at the top of the page:
* Circles (○) should be colored Blue.
* Triangles (△) should be colored Red.
* Squares (□) should be colored Green.
* Rectangles (▭) should be colored Yellow.

Step 2: Identify and Color the Shapes in the Big Design
Let's look at the large circular pattern in the middle:
1. Circles: There are circles around the outside edge and one right in the center. Color all of these Blue.
2. Squares: Inside the ring, there are four larger square shapes (top, bottom, left, and right). Color these Green.
3. Rectangles: Between the squares, there are long rectangular shapes pointing toward the center. Color these Yellow.
4. Triangles: The spaces between the rectangles and the inner circles are triangles. Color all of these small triangles Red.

Step 3: Identify and Color the Shapes in the Bottom Strip
Now look at the row of shapes at the very bottom:
1. Rectangles: On the far left and far right ends, there are two rectangles. Color these Yellow.
2. Triangles: In the middle section, there is a zig-zag pattern made of triangles. Color all of these triangles Red.

Final Answer:
Here is how you should color the page:
* Blue: All circles (the 6 on the outside ring, the 1 in the center).
* Green: The 4 squares inside the main design.
* Yellow: The 4 rectangles inside the main design and the 2 rectangles at the ends of the bottom strip.
* Red: All triangles (the ones inside the main design and the ones in the bottom strip).
