NCERT Class 4 Maths Chapter 8 Weigh it, Pour it: what it teaches

Your child moves to standard units of weight and capacity: 1 kilogram is 1000 grams, and 1 litre is 1000 millilitres. They read packet labels, fill a litre bottle from smaller bottles, and estimate weights before checking.

Why it matters later. Grams, kilograms, litres and millilitres are used in cooking, shopping and science throughout school.

250 ml250 ml250 ml250 ml= 1 L
Four 250 ml glasses fill one litre.
500 g1 kg500 g is half of 1 kg
Bigger number, smaller weight: check the unit.
0.750 kgweigh fruit: guess first
Guess the weight, then check on the scale.

You need

  • a kitchen scale
  • a 1 litre bottle and smaller bottles (200 ml, 500 ml)
  • packets with weights printed on them
  • a measuring cup

Tonight’s 10 minutes

  1. Read labels: which packets are in grams, which in kilograms, which in ml?
  2. Fill the 1 litre bottle from a 500 ml bottle. How many times? Then from a 200 ml bottle.
  3. Weigh fruits on the kitchen scale. Guess first, then check.
  4. Find packets that add up to about 1 kg.

Words to use

  • kilogram (kg)
  • gram (g)
  • litre (L)
  • millilitre (ml)
  • 1000
  • about
  • estimate

Watch for

  • Thinking 500 g is more than 1 kg because 500 is a bigger number. Put a 500 g packet and a 1 kg packet side by side and lift both.
  • Mixing weight and capacity units. Weight: kg and g. Liquids: litres and ml.
