This video lesson introduces students to the parts of a circle. The video starts off with reviewing the definition of circle. The video also covers key terms such as radius, diameter, chord and circumference. I use this lesson as part of a grade 7 measuring circles unit of study. This video may be used as part of a flipped classroom or incorporated into your daily lessons. This video is aligned to standards 7.G.A and 7.G.A.2 Enjoy!
