Mathematics + Various knowledges = Integrated textbook


Well Done Mathematics! is an integrated textbook helping children to have interest in learning math with a story of the African boy Didier, who loves football. It helps students to learn important values such as ‘fairness’ and ‘cultural diversity’ as well as the solar system and the sea through the Didier’s adventure. It was made by volunteer educators, illustrators, designers, translators, and individual donators of Well Done Project.














Evaluation of Well Done Mathematics!



She is one of the curriculum committees of Western Cape Education Department (WCED) in South Africa. She wanted to use the book in school, especially for boys to get interested in math class when I gave some books to them after having a meeting in their office building in Cape Town.

Why_ After building the water pump in DR Congo, I could visit Ntembe basic school in a countryside of Zambia by invitation of World Vision Korea in 2010. In the school, I found that there were no books or tools for the students. So I wondered what I can do for them and found the letter of Yaguine and Fode, who appealed to the world to help children in Africa and froze to death on an airplane flying from Guinea to Belgium in 1999 while I was searching the internet.


Since then, I thought about making a book which helps children to broaden their horizon with reasonable price and started to make it gathering participants such as educators, illustrators, and translators through SNS and fundraised money for the project by conducting some crowdfunding projects.
