ACTIVITY-1
What To Do?
To estimate and measure the length of small objects using a metre long paper strip
What We Need?
Chart paper, glue stick, pencil, ruler, a pair of scissors and cardboard
How To Do?
• Cut five strips of width 2 cm and length 20 cm from the chart paper.
• Paste the strips one after the other on the cardboard to make one long strip. Cut
the cardboard along the edges of the strip.
• Make markings 1 cm apart on the strip using a ruler. Your metre scale is ready.
• Take a few items like a book, lunch box, duster, pencil, chalk, etc. Guess and write
the lengths of these objects.
• Then measure the lengths of these items using your metre scale and record your
observations. Ignore the part of the object that cannot be completely measured
with the strip. See how close your guess was to the actual measurement.
Extension: You can also measure the length of your classroom, blackboard, table, etc.
and make a list of things which are more than 1 metre in length and those which are
less than 1 m in length.
ACTIVITY-2
What To Do?
To measure the capacity of different containers using non-standard units
What We Need?
Bottles, cups, buckets, white sheet of paper and a pencil
How To Do?
• Pour one cup of water into a bottle. Mark its position with a rubber 4 cups
band as shown. 3 cups
• Estimate and guess how many cups of water will fill the bottle. 2 cups
• Now fill the bottle by using cups and find the actual number of 1 cup
cups of water required to fill the bottle.
Actual number of cups = ________ Estimated number of cups = ________
Extension: Use the bottle to fill a bucket. Estimate how
many bottles of water will be needed to fill the bucket
by guessing? Check by finding the actual number of
bottles of water required to fill the bucket.
Estimated number of bottles = _________ bottles
Actual number of bottles = _________ bottles
