Self Direction in ECSD

How can I allow my students to be self directed during a math class? In an environment where everything needs to be modeled, and your evaluation scores depend upon a structured classroom, is it possible to allow students the freedom to develop new ideas within the math classroom? I find it odd that we expect our students to be self directed and intrinsically motivated while the the district expects the teachers to be guided by the ever-changing rubric and the extrinsic motivation known as performance pay.
