Here are some freewares for educators/schools and parents also. They’re for K12 students. I’m going to post three for now and I’ll be posting the others next time.
The arcade oriented FoodForce, created by the United Nations’ World Food Programme, gets you to join a team of UN experts and help them fight hunger on the fictional island of Sheylan in the Indian Ocean, which is suffering from both drought and civil war.
FoodForce contains six different missions:
1. Air surveillance: Locating hungry people from a helicopter.
2. Energy pacs: Learn how to produce a balanced diet for your citizens, consisting of rice, cooking oil, beans, sugar and salt within a budget of only 30 cents per day.
3. Air drop: Drop your food supplies in a target zone. Don’t forget to compensate for wind direction!
4. Locate and dispatch: Co-ordinate supplies of purchased and donated food from around the world.
5. Food run: Lead a UN food convoy to a depot, dealing with dangers like landmines and road blocks.
6. Future farming: Use food aid to help a village develop over 10 years, by investing it carefully for nutrition, education, training, schooling, “food for work” and HIV/AIDS treatment.
GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and
calculus. It is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.
On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum. It can also be used to create dynamic worksheets. These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa. Visit Math4AllAges for great topics on GeoGebra.
Minisebran contains alphabet exercises, number exercises and doodle activities. It is perfect for toddlers and kids up to 5 years old who are learning the basics of using a computer, keyboard and mouse.
The design is in bright colors on a black background. The program runs in full screen mode. It is multilingual and runs in Catalan, English, French, Greek, Afrikaans and Swedish.
