This book brings together the first book collection of African research in mathematics education in multilingual societies and chronicles current research in different linguistic contexts across the African continent, (including Algeria, Namibia, Malawi, Morocco, Rwanda, South Africa) on issues of multilingualism in mathematics education, but more importantly, it foregrounds pertinent issues for future research. With many of the authors building on earlier path-breaking African research, the book is a unique contribution of careful thinking through how linguistic diversity and multilingualism manifest in ways that differ from one geopolitical context to another. This volume is an important contribution to the growing recognition of multilingualism as the global 'linguistic dispensation' in mathematics education. It is an invitation to how we might (as an international community where more and more multilingualism is the norm rather than an exception) pay more attention to the multilingual agency and capabilities of both students and teachers in order to better harness the epistemic potential of multiple languages in contexts of language diversity in mathematics education.
