Game-based resources provide opportunities to consolidate and develop a greater knowledge and understanding of both mathematical concepts and numeracy skills, which present opportunities and challenges for both teachers and learners when engaging with subject content. For learners for whom the language of instruction is not their first or main language, this can present challenges and barriers to their progress. This requires teachers to reconsider and adapt their teaching strategies to ensure the needs of these learners are fully addressed, thereby promoting inclusion and inclusive practices. The Handbook of Research on International Approaches and Practices for Gamifying Mathematics provides relevant theoretical frameworks and the latest empirical research findings in teaching and learning mathematics in bilingual/plurilingual education by using active methodologies, specifically gamification and game-based learning and teaching. Covering a wide range of topics such as e-safety, bilingual education, and multimodal mathematics, this major reference work is ideal for policymakers, researchers, academicians, practitioners, scholars, instructors, and students.
