CPM Math 3 (Core Connections, Integrated III) is the third course in CPM’s integrated high school mathematics series, designed to prepare students for college-level math and advanced STEM coursework. It extends work from Math 1 and Math 2, emphasizing the interconnectedness of algebra, geometry, statistics, and probability. Students deepen their study of functions, including polynomial, rational, logarithmic, and trigonometric functions, focusing on graphing, transformations, solving equations, and modeling real-world contexts. Geometry concepts expand to include circles, conic sections, and the geometry of three-dimensional figures, as well as advanced applications of trigonometry, such as the Law of Sines and Law of Cosines. Algebraic fluency is strengthened through operations with complex numbers, sequences and series, and solving systems of equations.
The course also places a strong emphasis on data analysis, probability models, and statistical inference. Students explore conditional probability, normal distributions, margin of error, and the design and interpretation of statistical studies. Throughout Math 3, CPM’s problem-based, collaborative learning approach encourages students to explain their reasoning, critique the reasoning of others, and apply strategies to novel situations. Technology and visual models are integrated to support conceptual understanding, while real-world and interdisciplinary problems help students see the relevance of mathematics beyond the classroom. By the end of the course, students are equipped with the mathematical reasoning skills necessary for precalculus and beyond.
