This document provides a self-learning module on circles for 6th grade math students. It introduces the key elements of circles like radius, diameter, arc, and circumference. Students learn to draw circles using a compass, identify the center, and measure radii, diameters, circumferences and their relationships. Pictures are provided for students to label circle elements correctly and understand concepts like chords, arcs, semicircles through visuals. The module aims to teach students about circles through interactive exercises and self-evaluation.
