Did we wonder how to measure the height of a tree?
We don’t know what all is in measuring tape? We observed the tree, it was very tall, we did not know how to measure?
We choose a tree that we could climb.
One child climbed the tree, another child gave the tape to his hands, one child measured the total length of tape, it was short so she knotted two tapes, still it was short and then joined another tape. Finally, the height of the tree was measured. We did not know what is inch? what is meter? what is centimeter?
We approached Google baba and we found conversion in meters. We just played with measurements!
