Circumference of a Circle
Students will define circumference and radius/diameter, and calculate the circumference of circles using the formula C = πd or C = 2πr.
Key Questions
- Explain the meaning of pi (π) in relation to a circle's circumference and diameter.
- Differentiate between radius, diameter, and circumference.
- Predict how doubling the diameter of a circle affects its circumference.

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.
