Effects of formulating math problems on primary students` performance

In maths classrooms at every level in all countries of the world, students can be observed solving problems. The quality and genuineness of these maths problems has been the theme of many arguments and debates in recent years.In this article we are going to show and compare the performance of primary school students using our experiment. We collected 20 second-grade students and conducted a lesson with traditional way of teaching. At next lesson we had took an examination to check if our students have comprehended the material and  got the results. The next lesson they  were given tasks to pose problems related to the same topic we had learned last time and took  another exam with the same level of difficulty and a slight change of numbers and got the results as well. The change and progress of students impressed us.
