Different activities will help children to guess and estimate weights of familiar things they see at home, at the grocery shop, etc. Guessing the weights of animals is an enjoyable exercise and helps them get a feel of larger weights. Teachers must bring a balance to class and give them a chance to weigh things themselves. 
Look for Weights and Balances
Make a trip to your nearest junk dealer, vegetable shop and grocery shop. Have a look at the weights they use. Find out:
i) Who uses the biggest weight?
ii) Who uses the smallest weight?
Have you seen any of these balances?
In which shop would you find the following types of weights?
Discuss with your friends.
