Mean of Grouped Data (Step-Deviation Method)
Students will calculate the mean of grouped data using the step-deviation method.
Key Questions
- Explain the advantages of using the step-deviation method for large frequency distributions.
- Analyze the role of the class size (h) in the step-deviation method.
- Construct a scenario where the step-deviation method significantly reduces calculation complexity.

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.
