**What do you notice?**
- You might notice that the number of shaded squares is increasing at each new step.
- You might notice that the number of shaded squares increases by the same amount at each step.
- You might notice that the pattern’s shape stays the same.

**What do you wonder?**
- You might wonder the number of shaded squares in Step \(4\) or maybe in the \(100^{th}\) step.
- You might wonder if this pattern continues in the same manner after Step 3.
- You might wonder if there is a rule or equation that can predict the number of shaded squares for any step.
