A standing board was placed where the students could see it, and a question was written on the board that would make mathematics interesting and fun for each day.  However, in order to keep the curiosity and excitement alive, the answer to the question was not given that day, it was left to the next day.  The students went to the blackboard again the next day to learn the answer to the question.  While learning the answer of the previous day, they encountered a new question and tried to solve it.  While this process continued in this way, the students solved the mathematical questions as if they were  solving a puzzle. In this way, the students participated actively in mathematics.
