Permutations and Combinations
Learn counting principles to determine the number of possible outcomes. Use permutations when order matters and combinations when it does not to solve complex probability problems.

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.

Understanding Independence and Conditional Probability
Explore the difference between independent and dependent events. Learn how the occurrence of one event can affect the probability of another, a concept known as conditional probability.

Conditional Probability and Independence
Use the formal definition of conditional probability to calculate probabilities. Apply the test for independence, P(A and B) = P(A) * P(B), to determine if two events are truly independent.

The Addition Rule
Learn to calculate the probability of one event OR another occurring. Apply the General Addition Rule, P(A or B) = P(A) + P(B) - P(A and B), paying special attention to mutually exclusive events.

The Multiplication Rule
Find the probability of two or more events occurring in sequence. Apply the General Multiplication Rule, P(A and B) = P(A) * P(B|A), and its simpler version for independent events.
