Strand: Geometry & Measurement
Curriculum: Determining circumference of a circle, establishing a connection between diameter, Pi and circumference, understanding the formula for circumference of a circle.
Used in a 'three-part' format, students during this lesson explore the concept of circumference of a circle. Students are able to access the problem through establishing a connection between a square and a circle, and determining if they have the same area if their perimeters (circumference) will be the same. Ultimately, students will develop a greater understanding of the relevancy of Pi, it's connection to Diameter and why we use both to solve for circumference. The lesson embeds inquiry based practices, critical thinking skills (decoding a puzzle), and accountable talk strategies (descriptive feedback using criteria).
Includes the hand out for students along with the lesson plan and manipulatives used to guide students throughout the problem. The task aligns with the Ontario curriculum's Achievement Chart for Mathematics (Easily adaptable to other areas such as Common Core).
