I made these animations, games and teacher tools to help my students understand and learn.
You are welcome to link to them if you find them useful.
Please give due credit.
Sadly Adobe has discontinued support for the Flash Player as 2021, and so the compiled .swf files no longer run in a browser.
There are other .swf players out there, but I'll leave that to you if you want to use these.
Comments and suggestions are welcome.
