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. 

We’re working on adding more non-Flash Mathlibs®, and you can see the first question set here! (Or click the image below!)

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.                           

~ Jessika Jake

 

Make your own silly math questions! Have fun while reviewing 4th Grade Math for the state tests. (Flash® is required.) You can also view MathLibs® FULL SCREEN (ad free) in a new window and try other fun math content below!

It’s easy to explore:

  • Click Math Libs above to choose between Multiplication MathLibs® (Grade 3) and Grade 4 MathLibs® sets. You can then generate your own silly math questions!
  • Click Lessons above to click through fun animated Grade 4 math lessons in: Numbers, Patterns, Measurement, Geometry, Graphing, and Probability. If you prefer to hear audio with the lessons, click here (also ad free).
