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.

Transformations and Symmetry
Students explore rigid motions and use them to define congruence. They will identify lines of symmetry and rotational symmetry in various figures.
8 methodologies
Triangle Congruence
Students establish criteria for triangle congruence (ASA, SAS, SSS) using rigid motions. They apply these criteria to solve problems and prove geometric relationships.
8 methodologies
Geometric Constructions
Students perform formal geometric constructions using a compass and straightedge. They will construct bisectors, perpendiculars, and regular polygons.
