Gr 6 Unit 8 Circles and Geometric Measurement

Unit 8 Circles and Geometric Measurement


Content Emphasis/ Big Ideas

This unit begins with students working with area and perimeter of triangles and rectangles. These concepts help build a foundation for exploring surface area and volume of three-dimensional figures in grade seven. Through exploration, students also derive that the value of pi (≈3.14) which is the value of the ratio of the circumference of a circle to its diameter. Students end the unit with finding the circumference and area of circles.
