Learning with TuxMath (free open source)

Very cool...

The original TuxMath game is a kind of pastiche of the old “Missile Commander” arcade game — fireballs descend from the sky, menacing your igloos (in TuxMath, the buildings on the ground are igloos with tux penguins in them). Each fireball is marked with a basic math fact problem, and you have to type in the answer and press “enter” to zap the problem. In this way, you fend off the attack and save your igloos.


Playing the “Tux of Math Command” game is a simple and fun way of practicing your basic arithmetic

It’s pretty simple, but the graphics are beautiful, the music is invigorating, and the pacing is excellent. It’s very easy to reach a “flow” experience, which keeps you going.

I’ve found that even as an adult, the game improves my own recall. The game levels start with very simple addition (even a first or second grader can handle these), and from there they work gradually up to harder and harder problems. At the highest level (“Commando”), the game is challenging even for me, because the problems are multi-step missing-value problems, and the time pressure makes it quite a challenge solve them before they hit.

Somewhere in the middle, it definitely helps my son.

2. If you are running a Debian-based system...

TuxMath should be in your distributions software repositories.

As root or using sudo, apt-get install tuxmath. And that should be it.

4. yeah, I installed it from the repos

which is why I didn't see the message. Still no excuse for not using a valid security certificate.

It appears that the admin at alioth.debian.org is using ca.debian.org as its Certificate Authority, which is not recognized as one of the "trusted roots" by Mozilla Firefox.
