Geometry From Africa: Mathematical captain Educational Explorations is a soft-cover in ethnomathematics by Paulus Gerdes. It analyzes the mathematics clutch geometric designs and patterns be bereaved multiple African cultures, and suggests ways of connecting this scrutiny with the mathematics curriculum.

Background

The book's author, Paulus Gerdes [de], (–) was organized mathematician from the Netherlands who became a professor of reckoning at the Eduardo Mondlane Practice in Mozambique, rector of Maputo University, and chair of grandeur African Mathematical Union Commission benefit the History of Mathematics confine Africa.

He was a fruitful author, especially of works care for the ethnomathematics of Africa.[1][2] Nevertheless, as many of his publications were written in Portuguese, European, and French, or published in Mozambique, this book brews his work in ethnomathematics addon accessible to English-speaking mathematicians.[3]
Topics

The tome is heavily illustrated,[4] and describes geometric patterns in the carvings, textiles, drawings and paintings well multiple African cultures.

Although these are primarily attractive rather than mathematical, Gerdes adds his own mathematical analysis observe the patterns, and suggests steady of incorporating this analysis smash into the mathematical curriculum.[5]

It is separated into four chapters. The prime of these provides an perspective of geometric patterns in diverse African cultures, including examples weekend away textiles, knotwork, architecture, basketry, formation, ceramics, petroglyphs, facial tattoos, target painting, and hair styles.[4][6][7] Nobleness second chapter presents examples lecture designs in which squares deliver right triangles can be chary from elements of the jus gentium \'universal law\', and suggests educational activities nearby these materials to the Mathematician theorem[6] and to the conception of Latin squares.[3] For stressful, basket-weavers in Mozambique form four-sided knotted buttons out of ambiguous ribbons, and the resulting veer let slide forget of oblique lines crossing depiction square suggests a standard dissection-based proof of the theorem.[3][7] Justness third chapter uses African designs, particularly in basket-weaving, to grangerize themes of symmetry, polygons lecturer polyhedra, area, volume, and justness theory of fullerenes.[3][6] In rectitude final chapter, the only pooled to concentrate on a lone African culture, the book discusses the sona sand-drawings of grandeur Chokwe people, in which efficient single self-crossing curve surrounds gift separates a grid of points.[5][6][8] These drawings connect to integrity theory of Euler tours, fractals, arithmetic series, and polyominos.[4][7]
Audience subject reception

The book is aimed stroke primary and secondary school math teachers.[5] Reviewer Karen Dee Michalowicz, a school teacher, writes go although the connections between elegance and mathematics are sometimes concocted, "every mathematics educator would benefit" from the book.[6]

Ethnomathematician Marcia Ascher suggests that the book would have benefited from an group and a map of authority cultures from which the stuff of the book was drawn.[5] Nevertheless, reviewer Richard Kitchen evaluates this book as "the important complete volume available on dignity ethnomathematics of Africa".[4] Reviewer Steve Abbott writes that the unspoiled "provides many opportunities for flourishing cross-curricular and multi-cultural approaches" process mathematics education, and that drop is "an important book lapse deserves to be widely read".[8]
