Abstract
Mathematical illusions and concepts can be more easily visualized and understood with the help of information and communication technologies (ICT). On the contrary, ICT development in Nepali classrooms (from elementary school to university) moves glacially. This study examines the role of ICT tools in mathematics and their features and importance in promoting meaningful learning in mathematics. Based on the literature available, this study found that GeoGebra, Google SketchUp, and Microsoft Mathematics are excellent ICT tools for visualizing mathematical concepts, creating 3D models, and discovering solutions and graphical representations of more complex mathematical concepts and/or illusions. This study also demonstrates the importance of these ICT tools in promoting mathematics teaching and learning from elementary school to the university level. Incorporating the ICT tools mentioned above for teaching and learning mathematics has positively impacted students' achievement in mathematics.
