Yesterday we did a fun project about a mapping in the complex plane that I saw from Dan Anderson on Twitter: That project is here: Dan Anderson Project part 1 When I asked the boys what they wanted to talk about this morning, they said that they wanted to talk more about Dan’s shapes. Instead … Continue reading Dan Anderson’s complex mappings part 2
I drove back to Boston from NYC today and was pretty tired when I got home. BUT, upon arrival I saw this incredible tweet from Dan Anderson: I had to ask Dan (and click through a few of the related tweets) to figure out what was going on, but the final shape in the Gif … Continue reading A neat complex number program from Dan Anderson
The best way to start off on this project is to say that I wish we’d done better with this one. Not that it went terribly or anything, I just think that Dan’s program is a great thing to use to talk with kids about Dragon curves, fractals, programming, and probably lots of other stuff, … Continue reading Dan Anderson’s Dragon Curve program
Saw this tweet from Dan Anderson today: I didn’t have the best math talks with the boys this morning and was sort of bummed out about it all day. Because the problem Dan posted has a really surprising and fun math connection in the solution I thought that going through it would help us end … Continue reading Talking through Dan Anderson’s mod 2 Pascal’s Triangle
I saw a tweet from Amy Hogan this morning that reminded me of an old project: The old project is here: And Grant’s video is here: Before we started the project today, I had my son watch Grant’s video. Here are some of his takeaways: Now we tried to see if we could find a … Continue reading Revisiting Grant Sanderson’s “fair division” video thanks to an Amy Hogan tweet
I saw an interesting tweet from Jordan Ellenberg earlier this week – here’s writing a new book on geometry and was asking for suggestions for neat geometry ideas people have seen: Having spent close to 10 years now searching for fun math ideas to share with kids, the tweet from Ellenberg was a good motivation … Continue reading 10 fun geometry ideas to share with kids – inspired by a Jordan Ellenberg tweet
A few weeks ago Grant Sanderson published this amazing video about fractal dimension: I’ve had it in my mind to share this video with the boys, but the discussion of logarithms sort of scared me off. Last week, though, at the 4th and 5th grade Family Math night the Gosper curve fractals were super popular. … Continue reading Sharing Grant Sanderson’s Fractal Dimension video with kids
[sorry for a hasty write up – had to be out the door by 8:15 this morning . . . ] Yesterday I saw the latest video from Grant Sanderson, and it is incredible! I couldn’t wait to share the “fair division” idea with the boys. I introduced the concept with a set of 8 … Continue reading Grant Sanderson’s “Fair Division” video shows a great math project for kids
My son asked me about recursive functions yesterday morning and I showed him Dan Anderson’s online tutorial: Even though Dan’s resource covers just about everything ( ha ha ) I thought maybe there was still something we could discuss this morning. So, I talked about the Fibonacci numbers. First we did a quick introduction: Next … Continue reading Recursive functions and the Fibonacci numbers
Over the winter break I began to think about collecting some of our 3d printing projects into to one post to highlight various different ways that 3d printing can be used to help kids explore math. The post got a little long, but if you are interesting in thinking about 3d printing and math, hopefully … Continue reading 3d printing ideas to explore math with kids
