"Bingo Event with Exponential Numbers" was held in the mathematics workshop in the 5th grade. In this activity, our students showed the square and cube of a natural number as exponential expressions and calculated its value. Our students calculate the value of the exponential expressions selected from the bingo bag. Then, they looked for this number on their bingo cards and tried to complete all the numbers on the bingo cards. In this activity, which our students followed with excitement until the last moment, the subject of exponential expressions was reinforced with fun.
