CPM Math 2 (Core Connections, Integrated II) is the second course in CPM’s integrated high school mathematics sequence, building on concepts from Math 1 and preparing students for Math 3. The curriculum blends algebra, geometry, probability, and statistics, emphasizing problem-solving, reasoning, and multiple representations of mathematical ideas. Students extend their understanding of functions—including quadratic, exponential, absolute value, square root, and piecewise-defined functions—by analyzing graphs, solving equations and inequalities, and modeling real-world scenarios. Geometry topics include transformations, similarity, right triangle trigonometry, and proofs involving congruence and similarity. Algebraic manipulation, factoring, and the use of different forms of equations are woven throughout, along with the continued development of proportional reasoning and modeling skills.
The course also deepens students’ ability to work collaboratively and justify their reasoning, a hallmark of the CPM approach. Statistical topics focus on interpreting and comparing data sets, understanding variability, and making inferences based on samples. Probability concepts include compound events, simulations, and theoretical probability. Throughout the curriculum, students engage in investigations that connect algebraic and geometric ideas, fostering conceptual understanding rather than rote memorization. Technology, visual models, and problem-based learning activities are integrated to help students see connections between mathematical topics and apply them to authentic contexts.
