 * Process:
 * 1) The idea here is to inculde several measuring units for practise.
 * 2) Initially instruct the students regarding the activity and its purpose.
 * 3) Group students into 3 in each.
 * 4) The teacher shall make packets of things as treasure and hide them in the school premises.
 * 5) The students shall pick chits containing clues to hunt and find the packets.
 * 6) 30 minutes is given to search.
 * 7) The students search packets and come back to classroom.
 * 8) The packets may contain cloth, ribbons, ropes, water, fruits, ingredients, vegetable , books , juice, stamps,envelops or any such measurable items.
 * 9) The students have to quickly decide which measuring mode they are going to use, measure and record their findings.
 * 10) They also have to measure the distance at which they found each and record the time taken to search.
 * Developmental Questions:
 * 1) What treasures did they find ?
 * 2) At what distance did they find ?
 * 3) How much time did they take to find ?
 * 4) What measuring instruments did they use ?, why ?
 * 5) How will they tabulate their results ?
 * 6) Can you list the purpose of each ?
 * Evaluation
 * 1) The teacher should analyse the students skill of documentation.
 * Question Corner:
 * 1) What are standard the units of length ?
 * 2) What are the standard units of weight ?
