How Big? How Heavy?
NCERT Math Magic for Class 5, Chapter 14, How Big, How Heavy, starts with children lifting packets and guessing which holds more. It builds volume by counting unit cubes that fill a box, connects cubic centimetres with millilitres and litres, and finds the volume of cuboids by multiplying rows, columns, and layers. Weighing with balances, comparing grams and kilograms, and filling jugs and bottles link size with weight. Children estimate, measure, and check how many small packets fill a big carton.
