OK. I gotta get me a TV.
I was working through some of the content for the Grade 9 curriculum and stumbled upon some YouTube videos that might be helpful. The teacher who does the demonstrations is lovely, although the comments below her vids aren’t particularly kind. If you show these to your students, consider using a full screen mode so they don’t see the nasty comments…. :o)
Try these instructional videos:
And for a lark, check out this “music video” that reviews the important parts of a circle (diameter, radius, pi, circumference, etc…). Hey – I’ll try anything at this point!
If anyone out there has any gems to share in the way of interactive applets to demonstrate the circle properties (tangent to a circle, inscribed angles, bisected chord, angles in an inscribed quadrilateral) I’d be most grateful!
