Creating and Interpreting Pie Charts
Construct and interpret pie charts to represent proportional data, calculating angles and percentages for each sector.
Key Questions
- Compare the information presented in a bar chart versus a pie chart.
- Analyze how the size of a sector in a pie chart represents its proportion of the whole.
- Design a pie chart to display the results of a survey, calculating the angle for each category.

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.
