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.

Basic Probability Rules
Students apply the addition and multiplication rules to calculate probabilities of simple and compound events. They use Venn diagrams and tree diagrams to model sample spaces.

Conditional Probability
Students calculate and interpret conditional probabilities using two-way tables and formulas. They determine whether two events are independent based on conditional probabilities.
