**Student Learning Targets**

- Habit 4: I can construct mathematical models.
- Habit 5: I can make strategic use of appropriate tools.
- Triangles 4: I can use special triangles to determine geometrically the values of sine, cosine and tangent for angles of 0, 30,45, 60 and 90 without a calculator.

**Something to Consider:**

## What special numbers can you see in your fascinating chart?
