The activities proposed throughout the book invite the reader to experiment and to explore the ‘rhythm’ and symmetry of the illustrations. Surprising results will be playfully obtained such as in arithmetic, a way to calculate quickly the sum of sequence of odd numbers. Children will live the beautiful mathematics of the Angolan sand drawings. Translation by Dr. Arthur B. Powell (Rutgers university). Answers to the activities are provided.The book can be used both in classrooms and at home. (Book also available in print)< Less

Aus dem Vorwort: Leoparden streifen durch die Steppe, Jäger verfolgen Antilopen, Hühner flüchten vor dem Fuchs, Schildkröten suchen sich ihren Weg ... Das Volk der Chokwe im... More > nordöstlichen Angola hat traditionsreiche Techniken entwickelt, um in Sandzeichnungen die typischen Strukturen dieser Pfade darzustellen ... Paulus Gerdes ... hat in diesem Büchlein die Pfade der Chokwe-Weisen nicht nur in anregenden Zeichnungen wiedergegeben und die Geschichten dieser Pfade erzählt, sondern auch erklärt, welche überraschenden mathematischen Strukturen darin ausgedrückt werden... Zugleich hat der Autor die anregenden Sandzeichnungen umgesetzt in Aufgaben, mit denen jugendliche Leser eigenständig die geometrischen Strukturen weiter erkunden und insbesondere Erkenntnisse über Graphen gewinnen können. Das Werk zeichnet sich durch eine vorzügliche Anschaulichkeit aus und führt die Leser in Denk- und Vorstellungsweisen einer afrikanischen Kultur ein.

Voor kinderen vanaf 8 jaar. “Hoe tekenen we een antilope waar een wiskundig patroon in zit? Hoe vindt de ooievaar zijn weg door het moeras en waar zit het ritme in de tekening van de leeuwin? ... More > Paulus Gerdes toont het ons. De Tsjokwe bevolking in Angola houdt ervan verhalen te vertellen en deze uit te tekenen met sporen in het zand. In dit verrassend boekje worden kinderen en jongeren ingeleid in de rijke zandtekeningentraditie van de Tsjokwe. Via verhalen komen zandtekeningen tot leven en worden kinderen gestimuleerd allerlei figuren te analyseren en na te tekenen waarbij ze een rijkdom aan meetkundige ervaringen opdoen. ... Paulus Gerdes biedt deze zandtekeningen aan niet alleen als rijke schemata voor het verkennen van meetkundige inhouden maar koppelt er ook procedures aan vast voor een originele exploratie van de getallenwereld.” Greet Van Keymeulen, Arteveldehogeschool, Gent (72 blz.)< Less
