“I enjoyed reading the book and I enjoyed my time solving the problems also by putting myself in young students’ shoes. I can see the benefit of using these problems as well as the suggested solutions in secondary mathematics problem-solving activities. I am planning to use some of these problems (and suggested solutions)with undergraduate, graduate and teacher students as a trigger for a discussion on problem-solving also with digital environments.” (Irene Biza, Research in Mathematics Education, Vol. 19 (3), 2018)“This book is an extensive summary/report of a three year project where schoolchildren were given problems to solve outside the usual classroom problems. … this study is invaluable in giving modern mathematical educators insights into adapting modern pedagogical techniques to reflect how young people solve problems. … all will find something that they can use to improve the effectiveness of their teaching.” (Charles Ashbacher, MAA Reviews, maa.org, May, 2016)
