Its always a pleasure spending time with kids. They are the best means to help us live in the present. However, let me caution, one can go nuts if one is trying to sit with the kids for their studies. It's over years I have learnt and still learning that the trick is it make them feel it's flowing in their way.
I was with my younger, who is in class 3, helping her understand the concept of "measurement". With a glass in my hand and patience in my mind I was trying to explain her the difference between "volume" and "capacity". The conversation went something like this:
Me: Now look at this glass. Say it is half filled with water. (In actual the glass was half filled with the peels of orange I had just eaten for evening snack). Can you tell me what is volume and capacity with respect to that?
She: No. You only tell me.
Me: See, the total quantity of liquid this glass can hold is capacity. And the water contained in the glass say in this case half the glass, is the volume. Did you get it?
She: No, volume is half the glass filled with orange peels.
Me: (Knowing that she was in a mood to go to play, and her friends were waiting for her, I softened), Darling, you are right. However, VOLUME is usually used for measuring liquid.
She: That's not right!
Me: Ah! why is that not right?
She: Amma, don't you know? VOLUME is used to measure the sound from the TV as well!
I burst out into laughter and thus SHE managed to turn up my volume......
