Mathematics is the science of reasoning.

‘Iolani School's mathematics curriculum reflects a commitment to carry out the mission of the school and to meet the needs and standards defined by national organizations of mathematics teachers. Course offerings and teaching methods accommodate diverse needs, talents, and learning styles and are aligned with the Curriculum and Evaluation Standards of the National Council of Teachers of Mathematics.

The goals of the mathematics program are to provide each student with a firm foundation of basic skills and to encourage each student to apply independent reasoning to solve mathematical problems. From grades K-12 the curriculum emphasizes problem-solving and logical thinking as well as computation. To reinforce communication skills, students begin solving word problems in the Lower School, and the Upper School implements the Geometry Learning Project. In both the Upper and Lower Schools technology enhances the learning of mathematics. At the upper levels students use graphing and scientific calculators for investigation, analysis and problem-solving.

The Lower School mathematics curriculum follows a spiraling sequence to address student needs, abilities, and interests. Review and reinforcement occur from grade to grade. Grades K-2 use hands-on activities and games to encourage critical and creative thinking. Children learn basic addition and subtraction facts as well as geometry, measurement, time, and money. Grades 3-6 strengthen problem-solving skills and accuracy in computation, and give greater attention to math vocabulary, estimation, and critical thinking.

In the Upper School mathematics curriculum, the students gain a solid foundation through two three-semester sequences encompassing Algebra, Analytical Geometry, and Trigonometry. All students must complete Algebra 2 and take mathematics through grade 11. We offer honors courses, three Advanced Placement courses, and independent study in advanced topics for qualified students.

Real-world problem solving reinforces the study of mathematics throughout the curriculum. Second graders walk on the football field and trace the length of the Statue of Liberty to learn about measurement. Fourth graders learning about ecology in social studies take water tallies to understand their water consumption and to realize the importance of conservation. Opportunities outside the academic curriculum enhance instruction in mathematics. Many ‘Iolani students have won distinction in national mathematics activities and exams, such as in the Continental Mathematics League and the American Mathematics Competition. Many students participate in interscholastic mathematics competitions. ‘Iolani teams have a long record of success, both in MathCounts at the intermediate grade level and in Math Team at the high school level.
