Besides basic computational skills, they require inspiring ideas, perseverance, creativity and imagination, logical thinking, and other problem-solving strategies.
Often there are small stories, intriguing problems, and surprising results, which encourage discussions with friends and family.
At the same time, both in France and all over the world, a widely supported movement emerged towards the popularization of mathematics.
In 1990, they decided to start a challenge in France under the name Kangourou des Mathématiques in order to pay tribute to their Australian colleagues.
The particularity of this challenge was the desire for massive distribution of documentation, offering a gift to each participant (books, small games, fun objects, scientific and cultural trips).
After that, Kangourou des Mathématiques invited mathematicians and organizers of mathematical competitions from several European countries.
In seven countries – Belarus, Hungary, The Netherlands, Poland, Romania, Russia, and Spain – teams of teachers decided to also organize the contest in 1994.
[10] In 2009, the Pittsburgh Post-Gazette noted that the competition was very popular in Europe, and was "finding its way into the United States".
In 1994, mathematicians from 10 countries met in Strasbourg (France) and founded the association Kangourou Sans Frontières with statutes registered in Paris on January 17, 1995.
