2. Integrated Pathway: Comprises three subjects—Math I, Math II, and Math III, involving the interleaved study of Algebra, Geometry, and basic Statistics across different grades.

The Integrated Mathematics approach redefines the landscape of high school mathematics education in the United States. In contrast to the traditional sequence of Algebra 1, Geometry, and Algebra 2, Integrated Math follows a unified progression as Math 1, Math 2, and Math 3. This approach seamlessly integrates algebraic, geometric, and statistical thinking across all three courses, fostering a continuous spiral of mathematical concepts for enduring comprehension.

While both pathways aim to instill a comprehensive understanding of fundamental mathematical principles over a three-year span, Integrated Math distinguishes itself by prioritizing the reinforcement of problem-solving and reasoning skills. Unlike the traditional model, which predominantly focuses on algorithmic mastery, Integrated Math challenges students to tackle real-world “math tasks,” highlighting a shift toward a more holistic and application-oriented approach to mathematical learning.
