FlashQard helps you to learn any subject that can be learned via a question and answer format. You write a question on a card and the answer overleaf in formatted text. You can also insert as many pictures as you wish. The reviewing method is known as the Leitner system, proposed by Sebastian Leitner in 1970s. This method is a well known and widely used method to efficiently use flash cards and to reduce the amount of study time needed. FlashQard can read your card's text (text-to-speech) as you go through your cards.
Marble is a Virtual Globe and World Atlas that you can use to learn more about Earth: you can pan and zoom around, and you can look up places and roads. A mouse click on a place label will provide the respective Wikipedia article. It's also possible to measure distances between locations or watch the current cloud cover. Marble offers different thematic maps: a classroom-style topographic map, a satellite view, street map, earth at night, and temperature and precipitation maps. All maps include a custom map key, so it can also be used as an educational tool for use in classrooms. For educational purposes, you can also change the date and time and watch how the starry sky and the twilight zone on the map change. Marble also features multiple projections: choose between a flat map ("Plate carré"), Mercator, or the globe.

garith is a game similar in spirit to BSD's "arithmetic" or TuxMath. The game asks you to perform a simple arithmetic operation within a certain time frame. It improves your skills by stressing the operations you get more frequently wrong or that longer to answer. The statistics are saved/restored across games, so that each game is tuned for your current arithmetic abilities.
