The book 'History as a Resource for Teaching Mathematics' by Iran Abreu Mendes highlights the importance of history in decolonization and its role in teaching mathematics. Mendes draws on over three decades of research to show how the history of mathematics can enrich teaching, learning, and teacher training. Inspired by Brazilian thinkers like Paulo Freire and Ubiratan D''Ambrosio, the book offers a transdisciplinary approach that encourages reflection on the objectives of mathematics education in multicultural and multilingual societies. It serves as a valuable resource for educators seeking inspiration and new perspectives.
