| 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. | | 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.

| + | # 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. |
