Numbers, numbers, everywhere!
o Do you have a phone at home? How many digits does its dial have?
o What is the Pin code of your locality? How is it useful?
o When you park a vehicle, do you get a ‘token’? What is its purpose?
o Have you handled 24 ‘carat’ gold? How do you decide its purity?
o How high is the ‘power’ of your spectacles?
o How much water does the overhead tank in your house can hold?
o Does your friend have fever? What is his body temperature?
You have learnt about many types of numbers so far. Now is the time to extend the ideas further.
