“The inclusion throughout both volumes of thought-provoking examples of RME authentic context tasks offers opportunities for the reader to engage in moments of guided reinvention, serving as models of particular mathematics content, as well as creating models for reflection on the meaning and potential offered by Realistic Mathematics Education. There is a little bit of something for everyone in these books, and they represent an important contribution to the growing body of literature in the field of mathematics education.” (Anne R. Teppo, Educational Studies in Mathematics, Issue 104, 2020)“The book is written for those familiar with the RME tradition. I judge that is the audience who will find this volume of most interest. … What this volume contributes more uniquely is the personal histories and comparative experiences of scholars working to build on the tradition.” (Paul Christian Dawkins, MAA Reviews, December 14, 2019)
