Probability is an important topic in the high school mathematics curriculum. However dealing with randomness is always a challenge for Vietnamese students because they have not been encouraged to use their intuitive abilities and they lack the experience needed to feel the likelihood of probabilities. To overcome this difficulty it is necessary to use simulation in the teaching and learning probability at school. This paper would like to introduce Monte Carlo simulation which is a method of solving probability problems through the use of experiments. This method should be used in teaching probability to high school students because it increases their practical experience and it teaches students how to apply probability when attempting to solve real world problems. This paper explains what Monte Carlo simulation is and why and how teachers should teach Monte Carlo simulation to high school students. Keywords Monte Carlo simulation model experiment teaching probability high school students. 1. Introduction Probability is an appropriate topic in the school mathematics curriculum and textbooks because it is an indispensable part of real life it supplies necessary tools to comprehend the world around us and it provides meaningful applications of mathematics at all levels 1 6 9 10 11 and 13 . In addition this topic can contribute to the mental development of students 5 6 and11 and it is inherently interesting exciting and motivating for most students 13 . Although probability plays an important role in the teaching of mathematics at school it is always a difficult for students due to the cognitive demands of dealing with randomness in contrast with the .
