Today Khan Academy is a free educational network, which offers more than 3500 videos and unites over 10 million of students from different parts of the world. The videos of the founder of the Khan Academy, Salman Khan are not very long, they last from 5 to 15 minutes. They cover an amazing number of topics – from basics of Arithmetic and Algebra to the electoral college and the French Revolution. School Chamoion team, located in Kharkiv, was inspired with the Salman Khan’s idea and decided to make its own contribution – to organize the process of translating videos into Russian and Ukrainian and adapting to the traditions of our educational system. Cooperating from the end of 2010 we are approaching the mark of 1300 videos on topics of different mathematics.
