South Dakota Mathematics II: Full Course Overview
Mathematics II is a core high school course in South Dakota that builds directly on the algebra and geometry skills from Mathematics I. The course is structured around South Dakota Math Standards and prepares students for advanced coursework in Mathematics III, pre-calculus, and standardized assessments including the SBAC.
Key Topics in Mathematics II
- Quadratic Functions and Equations: Students solve quadratic equations in one variable, graph parabolas, and explore properties of quadratic functions including zeros, vertex, and transformations.
- Polynomial Operations: Students add, subtract, and multiply polynomials, understanding that polynomials form a closed system under these operations similar to integers.
- Exponential and Logarithmic Functions: Students compare linear, quadratic, and exponential growth and express exponential solutions using logarithms with bases 2, 10, and e.
- Trigonometric Functions: Students work with radian measure, the unit circle, special triangles, and trigonometric identities including the Pythagorean identity sin²(θ) + cos²(θ) = 1.
- Geometric Similarity and Proof: Students use similarity transformations to establish triangle similarity criteria (AA), prove theorems about triangles, and apply trigonometric ratios to right triangles.
- Circles and Coordinate Geometry: Students derive equations of circles and parabolas, work with inscribed angles, and use coordinates to prove geometric theorems algebraically.
- Probability: Students explore conditional probability, independence, two-way frequency tables, the Addition Rule, the Multiplication Rule, and permutations and combinations.
How StudyPug Supports Mathematics II Students in South Dakota
Every Mathematics II topic listed above has a dedicated video lesson on StudyPug. Lessons are 5–15 minutes long and broken into short segments students can pause and replay. After each lesson, students practice with problems similar to what they'll see on class tests and the SBAC.
StudyPug is available on any device — computer, tablet, or phone — so students can get help at home, during a study period, or anywhere they need it. Parents can monitor progress and make sure their child stays on track with South Dakota Math Standards throughout the school year.
Sequences, Rational Exponents, and Number Systems
Mathematics II also covers arithmetic and geometric sequences, rational exponents, and the properties of rational and irrational numbers. Students learn to write sequences recursively and explicitly, rewrite radical expressions using rational exponents, and explain why sums and products of rational and irrational numbers behave the way they do. These topics connect algebra and number theory and frequently appear in standardized assessments.
Geometry and Modeling in Mathematics II
South Dakota Mathematics II students apply geometry to real-world modeling problems. They use volume formulas for cylinders, pyramids, cones, and spheres, identify cross-sections of three-dimensional objects, and apply concepts of density based on area and volume. Coordinate geometry topics include proving slope criteria for parallel and perpendicular lines, partitioning line segments, and computing perimeters and areas using the distance formula.
