The standard unit of length in maths is Metre. To build the understanding and the importance of bigger units such as metre and smaller units such as Centimetre, the students did an activity of 1 metre scale. To get hands on experience of this activity students of grade 3 first measured different objects in their surrounding from a small strip or scale of 10 cm such as , eraser, sharpener and school bag. Later they tried to measure the length of the corridor which was not feasible with a centimetre scale, so they used a 1m scale strip for that. It was a fun learning activity for the students.
