Grade 7 - Shape and Space
Standard 7.SS.1 - Practice identifying the different parts of a circle.
Included Skills: Geometry
Demonstrate an understanding of circles by: • describing the relationships among radius, diameter and circumference. • relating circumference to pi. • determining the sum of the central angles. • constructing circles with a given radius or diameter. • solving problems involving the radii, diameters and circumferences of circles. • Illustrate and explain that the diameter is twice the radius in a given circle. • Illustrate and explain that the circumference is approximately three times the diameter in a given circle. • Explain that, for all circles, pi is the ratio of the circumference to the diameter (C/d) and its value is approximately 3.14. • Explain, using an illustration, that the sum of the central angles of a circle is 360°. • Draw a circle with a given radius or diameter, with and without a compass. • Solve a given contextual problem involving circles.
