My younger son just started the section on lines in Art of Problem Solving’s Algebra book. By happy coincidence Dan Anderson shared this fun line math art program: I thought it would be fun to have my son play around with the program and just see what his reactions were. Here are his initial reactions … Continue reading Using Dan Anderson’s line art program to explore lines with my son

Dan Anderson made a really neat little complex mapping program today: This program allowed us to do a fun continuation of the project that we did over the weekend: Sharing Kelsey Houston-Edwards’s Complex Number video with kids Looking at the complex map z -> z^2 with kids So, with each kid tonight I had them … Continue reading Playing with Dan Anderson’s complex map program
I’m not sure of the history, so apologies for surely leaving out credit for everyone involved, but Dan Anderson published an really neat math program last night: Dan Anderson’s rotating polygon’s program This morning I had my younger son play with the program – it is just amazing to watch and hear what kids have … Continue reading Playing with Dan Anderson’s rotation program
Saw a neat tweet from Dan Anderson earlier in the week: Post publication note – Dan wrote to me to say that his program has an error in it and that this program from Martin Holtham has the error corrected: Our project with Holtham’s program is here: Using Martin Holtham’s Inversion Program These inversions are … Continue reading Using Dan Anderson’s inversion program with kids
After seeing our introductory Mandelbrot project from yesterday: An introduction tot he Mandelbrot set for kids Dan Anderson sent us a link to a wonderful set of Mandelbrot Set-related resources on his programming page: Today I had the boys play around with the “Mandelbrot Zoom” program: Dan Anderson’s program “Mandelbrot Zoom” It is really fun … Continue reading Playing with Dan Anderson’s Mandelbrot program
Got a great surprise in the mail yesterday! I decided to introduce Dan’s shapes to the boys by putting them on our whiteboard and seeing what the boys would do. My younger son went first and chose to slightly surprising shape to try to make out of the Gosper Island pieces: Next he wanted … Continue reading Dan Anderson’s Gosper curves
A tweet from Patrick Honner inspired one of our projects and a slew of programs illustrating the pattern in different ways: We used two from Dan Anderson in our project: That project is here: Using NumberPhile’s Freaky Dot Patterns video with kids In the project the boys struggled a little with understanding how many degrees … Continue reading Using Dan Anderson’s Moiré Patterns Program to talk about rotations
Saw this tweet from Dan Anderson yesterday: He’d been inspired by an article that Tim Chartier post to make an interactive Light’s out game. There’s no school today so my wife and kids are heading up to New Hampshire for a hike, so I used Dan’s program for a light little morning project with the … Continue reading Dan Anderson’s “Lights Out” game
We’ve spent the last couple of days studying divisors of integers – mainly the number of divisors and the sum of those divisors. This topic came to us via a “things you should know for math contests” list that math team at my older son’s school gave to the kids. We’ve used Mathematica to help … Continue reading A neat problem Dan Anderson shared with us
