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.

Quadratic Functions and Inequalities
Students explore the conditions for a quadratic equation to have real, repeated, or no roots. They also learn to solve quadratic inequalities and find the maximum or minimum values of quadratic functions.

Polynomials and Partial Fractions
Students learn to divide polynomials, apply the Remainder and Factor Theorems, and solve cubic equations. They also decompose rational expressions into partial fractions.
8 methodologies
Binomial Expansions
Students investigate the binomial theorem for positive integer powers. They learn to expand expressions and find specific terms within an expansion.
