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.

Quadrilaterals
Students study the angle sum property of a quadrilateral and the specific properties of parallelograms. The Mid-point Theorem is also introduced and proven.

Heron's Formula
Students learn to calculate the area of a triangle using Heron's formula. They apply this formula to find the area of various quadrilaterals by dividing them into triangles.
