Combinations and Grouping
Students investigate combinations where order does not matter. They apply combinations to solve complex grouping and committee-forming 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.

Permutations and Organized Counting
Students learn to use tree diagrams and the multiplicative counting principle to solve problems. They explore permutations of distinct and non-distinct items.

Introduction to Probability
Students calculate the theoretical probability of events using counting techniques. They compare theoretical probability with experimental probability.

Mutually Exclusive and Independent Events
Students analyze compound events to determine if they are mutually exclusive or independent. They use Venn diagrams and formulas to calculate probabilities of these events.
