Averages: Mean, Median, Mode (Grouped Data)
Students will calculate estimates for the mean, median, and modal class from grouped frequency tables.
Key Questions
- Explain why we can only estimate the mean from grouped data.
- Differentiate between finding the modal class and the mode from grouped data.
- Analyze the impact of class width on the accuracy of mean estimates.

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.
