Understanding Fractions of a Circle

In this math lesson, students learn to divide a circle into fractions: halves, fourths, and eighths. The teacher guides students through cutting circles into these fractions using folding and cutting techniques. The lesson also explores additional fractions like thirds and sixths, emphasizing understanding and practice. Students are encouraged to practice naming and recognizing these fractions.
