Intersections of Three Planes
Students use algebraic methods, including matrices or elimination, to determine the intersection of three planes. They interpret the geometric meaning of the algebraic solutions.

5E Model
The 5E Model structures lessons through five phases (Engage, Explore, Explain, Elaborate, and Evaluate), guiding students from curiosity to deep understanding through inquiry-based learning.
Unit PlannerMath Unit
Plan a multi-week math unit with conceptual coherence: from building number sense and procedural fluency to applying skills in context and developing mathematical reasoning across a connected sequence of lessons.
RubricMath Rubric
Build a math rubric that assesses problem-solving, mathematical reasoning, and communication alongside procedural accuracy, giving students feedback on how they think, not just whether they got the right answer.

Equations of Planes in R3
Students develop the vector, parametric, and Cartesian (scalar) equations of planes in three-dimensional space. They use normal vectors to define planes and find angles between them.
