Through the course of Level III Mathematics, students will investigate the real number system, discern the difference between proportional and nonproportional relationships, and recognize patterns in arithmetic sequences. They will also find and use the theoretical probability of compound events and use measures of central tendency to describe a set of data. Then they will investigate geometric transformations (translations, dilations, and reflections) in the coordinate plane; use different models to simulate events; and review important concepts in preparation for Algebra I.
