The definition, agreement, and practical use of units of measurement have played a crucial role in human endeavour from early ages up to this day. Different systems of units used to be very common. Now there is a global standard, the International System of Units (SI), the modern form of the metric system.

*Process:
# The idea here is to inculde several measuring units for practise.
# Initially instruct the students regarding the activity and its purpose.
# Group students into 3 in each.
# The teacher shall make packets of things as treasure and hide them in the school premises.
# The students shall pick chits containing clues to hunt and find the packets.
# 30 minutes is given to search.
# The students search packets and come back to classroom.
# The packets may contain cloth, ribbons, ropes, water, fruits, ingredients , vegetable , books , juice or any such measurable items.
# The students have to quickly decide which measuring mode they are going to use, measure and record their findings.
# They also have to measure the distance at which they found each and record the time taken to search.
*Developmental Questions
