PEC Activity: To learn that decimal point does not move but only appears to have moved using chairs.

Four students were called up and allowed to sit as shown in picture 1 where first student represents Tens place, second student represents Ones place, third student represents tenth place and fourth student represents hundredth place. The big chair represents the decimal point. Now they were told to shift one place to their right. Now place of each student ( representing different digits changed but the position of chair ( representing decimal point) does not change. So it is concluded that decimal point does not move but only appears to have moved.
