This extremely user friendly PowerPoint has animated step-by-step directions on circle properties, conjectures, theorems, formulas, coordinate Geometry, practice, and word problems. 54 slides with animations allow you to control the pace and amount of content. It is often color-coded, and helps streamline the learning process. This PowerPoint could replace what is typically the tenth chapter of high school Geometry textbooks or help supplement them. I utilize this PowerPoint in my classroom which completed this school year with a 91% pass rate on the Florida Geometry End of Course Exam (compared to the state average of 63%).

You will find the easy to understand definitions, many example problems, and a huge number of practice slides extremely useful in assisting instruction. Content covered includes circles, radii, diameters, chords, central angles, inscribed angles, tangents, semicircles, major arcs, minor arcs, circumference, area, area of shaded sectors, equations of circles and much more. I have spent well over one hundred hours working on this resource, and it is more comprehensive and accessible than anything I have been able to find on the internet. Click through and see for yourself. I plan on posting 12 PowerPoints (one for each chapter in our textbook). Whether you are a high school, middle school, or elementary school math teacher, you will find this to be an engaging tool. A person could easily teach him/herself about circles with this PowerPoint. Enjoy!
