Vietnamese mathematics teachers continue to waste time to equip students which specified in the textbook and give them the process. Students are not encouraged to discover the challenging exercises that require practicable problem solving ability and complicated thinking formulas so they are not interested in Math. The problem is that - Why is it so difficult to teach Mathematics using practical situations - Can Vietnamese teachers teach Mathematics using practical situations - How can high school math teachers learn to teach Mathematics using practical situations To answer three above questions and figure out solutions for teacher to organize teaching case associated with practical situations this article shows several researches and recommendations. Keyword Mathematics teaching method practical situations high school teaching case learning case. 1. Introduction In the real life mathematics knowledge is frequently used. Having solid mathematics background helps people calculate or estimate rapidly and have logical thinking to solve well not only academic problems but also daily ones. In high school besides being useful in learning Maths Physics Biology Chemistry mathematics knowledge also provides students many chances in forming and developing key competencies namely calculating logical thinking problem solving self-study communication cooperating self-control and technology applying skill Tran Kieu and co-authors International senimar of capacity orientation training s report Ministry of Education and Training 2012 Recently in teaching method innovation wave helps people realize the goal of teaching .
