Measures of Spread: Range and Interquartile Range
Students will calculate the range and interquartile range to measure the spread or consistency of data sets.
Key Questions
- What does the range or interquartile range tell us about the consistency of a data set?
- Compare the advantages and disadvantages of using the range versus the interquartile range.
- Predict how an outlier might affect the range but not the interquartile range.

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.
