Geometry that builds mathematical thinkers

The new TEKS Geometry course emphasizes reasoning, logic, and proof. Students begin by exploring patterns and relationships, then progress to writing formal arguments. They’ll practice forming conjectures, constructing examples and counterexamples, and developing complete geometric proofs.

Key features include

• scaffolding for geometric constructions, starting with guided diagrams,
• application of triangle congruence and angle relationships,
• discovery of key principles like Cavalieri’s principle, and
• real-world connections that strengthen spatial reasoning.

Students aren’t just solving problems—they’re learning to think like mathematicians.

Precalculus that prepares for college and beyond

Khan Academy’s TEKS-aligned Precalculus course is built to support college readiness. It offers a full scope of content, from polynomial and rational inequalities to conic sections, parametric equations, and recursive sequences.

Highlights include

• clear, structured progression from foundational to advanced topics,
• new, targeted exercises with built-in feedback,
• focus on polar and parametric graphing, trigonometric identities, and transformations, and
• support for deep understanding of functions and their behaviors.

This course helps students make meaningful connections between algebraic and geometric concepts as they prepare for calculus and STEM pathways.

Built for flexibility and deeper learning

Both courses are designed to support multiple instructional models, whether you’re teaching whole-group lessons, working with small groups, or assigning independent practice. Every lesson includes instructional videos, interactive practice, and concept-based articles that support differentiation.

Students benefit from

• immediate, detailed feedback on every task,
• opportunities to revisit and build on key ideas, and
• a consistent structure that promotes confidence and progress.
