ACCESS TO ALL LESSONS AND VIDEOS LIE AT THE BOTTOM OF THIS SCREEN
During October 10 -17, 2017 a global phenomenon occurred. It was the world’s inaugural Global Math Week.
Over a million students and teachers from 168 different countries and territories experienced the uplifting joy of Exploding Dots. (And it has since grown to well over 4 million!) All was grassroots. All was volunteer. And all was propelled by a beautiful global community educators and math lovers simply wanting to share the joy and wonder of meaningful mathematics.
From our survey:
96.8% of teachers agreed or strongly agreed that Exploding Dots helped students see mathematics as more approachable, 96.6% as more enjoyable, 96.1% as making sense, and 93.1% as helping students be more confident in mathematics.
75.5% of teachers said that Exploding Dots changed their own perception of mathematics in some way with 97.7% agreeing or strongly agreeing that Exploding Dots made mathematics more enjoyable, 97.3% as more approachable, and 96.0% as more understandable.
You too can enjoy the wonders of Exploding Dots, here, in this course, or with the web app powered by Scolab.
By popular demand we are doing it again! Join us as we reach 10 million students across the globe!
Scroll down to see and access the Exploding Dots chapters. Play with them at your leisure. (Warning: When you start one, you won’t want to stop!
It all begins with a story that isn’t true:
When I was a young child I invented a machine (not true) that was nothing more than a series of boxes that could hold dots. And these dots would, upon certain actions, explode. And with this machine, in this non-true story, I realized I could explain true things! In one fell swoop I explained all the mathematics of arithmetic I learnt in grade school (true), all of the polynomial algebra I was to learn in high-school (true), elements of calculus and number theory I was to learn in university (true), and begin to explore unanswered research questions intriguing mathematicians to this day (also true)!
Let me share this story with you. See how simple and elegant ideas connect to elegant and profound ideas in mathematics as a whole. See how these ideas will COMPLETELY REVOLUTIONIZE your thinking of school arithmetic and algebra and beyond! This mathematical story will knock your socks off!
A one-hour Exploding Dots video of a lecture at Scottsdale Community College is here.
