About This Topic

Using tree diagrams and possibility diagrams to calculate probabilities for multiple independent events.

Key Questions

  1. Explain how to distinguish between independent and dependent events in a real-world scenario.
  2. Justify why we multiply probabilities along branches for independent events.
  3. Design a tree diagram to represent the outcomes of two independent events.

Planning templates for Mathematics

Lesson Plan

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 Planner

Math 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.

Rubric

Math 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.
