The triangle inequality theorem is coming soon in 7th grade. We'll use physical tools (pasta) and virtual ones to explore both the theorem and how often we can make a triangle when breaking a line in 2 random spots: http://youtube.com/watch?v=d6CQQEHpm18
The first talk in the Mathigon Guest Speaker series was last week. Dr. James Tanton shared 12 proofs that 2 = 1. It was a joy-filled and engaging session. Watch the talk at https://www.youtube.com/watch?v=JbbU4GgpXLk. I think you'll find it worth your time! Sign up for future events in the Guest Speaker Series at mathigon.org/events.
The next Mathigon webinar will focus on Exploring Data Science on Polypad. We'll explore the graphs and chart features and work through some activities together. We may even preview some upcoming features! Next Wednesday, Oct 13th at 7 PM EDT. Sign up at mathigon.org/events. Hope to see you there!
The interactive animations in the Introduction to the Circles and Pi course can help students visualize the proof for the formula of the area of a circle.
