Interpreting Measures of Spread (Range)
Students will calculate and interpret the range of a data set to understand its spread.
Key Questions
- Analyze how the range provides insight into the variability of a data set.
- Justify why a small range indicates more consistent data.
- Predict how adding an outlier will affect the range of a data set.

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.
