Students can celebrate being "100 days smarter" by coloring the shapes and completing the graph below.

Problem Description:

The task involves counting and coloring shapes within the number "100" and then recording the counts in a graph. The shapes to be counted are triangles (△), squares (□), stars (★), and circles (○). Each shape should be colored according to the provided color key:

- Triangles (△): Red
- Squares (□): Green
- Stars (★): Yellow
- Circles (○): Blue

Solution Steps:

#### Step 1: Identify and Count the Shapes
We need to carefully count each type of shape within the number "100."

1. Triangles (△):
- Carefully scan the image for all triangles.
- Count them one by one.

2. Squares (□):
- Look for all squares in the image.
- Count them one by one.

3. Stars (★):
- Identify all stars in the image.
- Count them one by one.

4. Circles (○):
- Find all circles in the image.
- Count them one by one.

#### Step 2: Color the Shapes
Using the color key, color each shape accordingly:
- Triangles (△) in red.
- Squares (□) in green.
- Stars (★) in yellow.
- Circles (○) in blue.

#### Step 3: Record the Counts in the Graph
After counting each shape, record the total number of each shape in the corresponding row of the graph at the bottom of the page.

#### Step 4: Verify the Counts
Double-check the counts to ensure accuracy.

Example Counting (Hypothetical):

Let's assume the following counts after careful examination:
- Triangles (△): 15
- Squares (□): 10
- Stars (★): 20
- Circles (○): 5

#### Step 5: Fill in the Graph
In the graph section:
- For triangles (△), shade or mark 15 boxes.
- For squares (□), shade or mark 10 boxes.
- For stars (★), shade or mark 20 boxes.
- For circles (○), shade or mark 5 boxes.

Final Answer:

After completing the steps above, the task is solved by:
1. Counting and coloring the shapes.
2. Recording the counts in the graph.

If you provide the actual counts from the image, I can help fill in the exact numbers for the graph. Otherwise, the process described above is the solution approach.

Final Answer:
\boxed{\text{Follow the steps above to complete the task.}}
