Measures of Variability: Range and IQR
Students will calculate and interpret the range and interquartile range (IQR) of a data set.
Key Questions
- Explain what a large range suggests about the consistency of a data set.
- Differentiate between range and interquartile range as measures of spread.
- Analyze how outliers affect the range and IQR of a data set.

Planning templates for Mathematics
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.
