Along with the 6th and 7th in Isaiambalam school, we wanted to estimate how far one Km would be. All the students made a guess and wrote down their check point on a route from their class.
The children wrote down how far their guess was compared to a Km, and took other nine checkpoints of other children, when they went back to class they decided to convert each checkpoint to meters, decameters, and hectometers.
