Look around your house and identify objects that are about half a kilogram and quarter of a kilogram. Feel these things with your hand and guess what other things are a half or quarter kilogram. List the objects that are about a quarter kilogram and a half kilogram. Verify with the 1 kilogram salt packet.
Objects about half kilogram (½ kg): a small packet of rice a bundle of vegetables a small bag of pulses 2-3 medium apples a small packet of sugar
Objects about quarter kilogram (¼ kg): a small packet of tea a bar of soap a small packet of spices 1 medium apple a small bundle of leafy vegetables
Verification: 2 half-kilogram objects should balance with 1 kilogram. 4 quarter-kilogram objects should balance with 1 kilogram.
Explanation
The chapter encourages children to explore their homes and identify objects weighing half kilogram and quarter kilogram. By comparing with a 1 kg salt packet, children can verify their estimates and understand the relationship: 2 × ½ kg = 1 kg and 4 × ¼ kg = 1 kg.
Solution Steps
Identify objects around the house weighing about half kilogram (½ kg).
Identify objects around the house weighing about quarter kilogram (¼ kg).
Verify estimates by comparing with a 1 kilogram salt packet.
Confirm: 2 × ½ kg = 1 kg and 4 × ¼ kg = 1 kg.
