MathLibs® – Free for Over a Decade!
Sorry, after almost 2 decades of offering Mathlibs® for free, Adobe discontinued the Flash Player, so now it’s not possible to view these lessons and games on the web any more.
I’m working on adding more non-Flash Mathlibs®, and you can see the first question set here!
If you have a PC, you can purchase the .exe version of Mathlibs® for $9.99 here. It breaks my heart that Flash is gone. I hope to be able to load more free math games onto this site in the future.
