a) Give informal arguments for the formulas of the circumference of a circle and the area of a circle using dissection arguments and informal limit arguments.

Learning Targets /Success Criteria:
LT: I can find the area and circumference of a circle.
SC:
• I can find the circumference of a circle given the radius or diameter.
• I can find the radius or diameter of a circle given the circumference.
• I can find the area of a circle given the radius or diameter.
• I can find the radius of a circle given the area.

Introduction/Connection (Activator): students will be asked what they remember about area and circumference of a circle.

Direct Instruction/Guided Practice:
• Guide students in completing area/circumference of circles foldable (attached).
• Guided/independent practice: practice w/s on area/circumference of circles (attached).

Independent Practice/Collaboration/Differentiation
--differentiation: Graphic organizers, foldables, color coding lines/segments, one-on-one assistance for struggling students, accelerated practice for higher performing students, partner work, student-led teaching/review.

Summarizer/CFU: TOTD
