In response to changes in state standards, a district revises its K–12 mathematics curriculum. The high school principal should pursue which strategy first?

• A. Organizing curriculum alignment between members of the mathematics department and their counterparts from district middle schools
• B. Introducing new textbooks without alignment
• C. Focusing on non-mathematics subjects
• D. Increasing class size

Answer: (A)

Vertical alignment of the curriculum across grade levels is the essential first step when standards change. By organizing how concepts progress from middle school into high school, the district creates a shared framework that clarifies what students should know at each point and how each course builds on prior knowledge. This alignment helps teachers plan coherent units, set consistent pacing, and design assessments that truly measure growth, ensuring a smooth transition for students and avoiding gaps or redundant topics.

Introducing new textbooks without alignment wastes resources and can create mismatches between what is taught and what students are expected to know. Focusing on non-math subjects or merely increasing class size does not address the need for a coherent math program that meets the new standards. Starting with curriculum alignment lays the foundation for effective implementation, after which resources, assessments, and targeted professional development can be aligned to support the change.
