| − | *Estimated Time : 1 hour
| |
| − | *Materials/ Resources needed:
| |
| − | # Weighing pan with measures of 1 kg, 500gm, 250gm and 100gm and 50gm.
| |
| − | # Digital scale
| |
| − | # Postal scale.
| |
| − | # Measuring cans of 1 litre, 500ml, 250 ml, 100ml,
| |
| − | # Measuring tape, Ruler.
| |
| − | # Watch or stop clock.
| |
| − | # Paper and pen.
| |
| − | *Prerequisites/Instructions, if any
| |
| − | # The students should have been introduced to the concept of formal measurements by conducting an activity on using standard measuring instruments.
| |
| − | # They should understand the importance of standard measurements and distinction between standard and non-standard units of measurements.
| |
| − | # They should be well versed with standard units and subunits.
| |
| − | # They should know unit conversions.
| |
| − | # They should have the skill of measuring and recording accurately.
| |
| − | # They should be aware that comparisons can be made only between similar measuring units.
| |
| − | *Multimedia resources
| |
| − | *Website interactives/ links/ / Geogebra Applets
| |
| − | *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, stamps,envelops 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:
| |
| − | Ask the students to write on
| |
| − | # What treasures did they find ?
| |
| − | # At what distance did they find ?
| |
| − | # How much time did they take to find ?
| |
| − | # What measuring instruments did they use ?, why ?
| |
| − | # How will they tabulate their results ?
| |
| − | # Can you list the purpose of each ?
| |
| − | *Evaluation
| |
| − | # The teacher should analyse the students skill of documentation.
| |
| − | *Question Corner:
| |
| − | # What are standard the units of length ?
| |
| − | # What are the standard units of weight ?
| |
| − | # How are liquids measured ?
