How to teach Class 3 Maths Chapter 11, Filling and Lifting, at home

NCERT Class 3 Maths Chapter 11 Filling and Lifting: what it teaches

Which glass holds more? Pour them into same-sized glasses to find out. Your child compares containers, uses a 1 litre bottle as a unit, and compares weights by lifting and with a simple balance.

Why it matters later. Litres and weight comparisons lead to millilitres, grams and kilograms in Class 4.

Pour into identical glasses to compare fairly.

Size does not tell weight; the balance does.

You need

  • a 1 litre water bottle
  • glasses, bowls, a jug and a bucket
  • a clothes-hanger balance or a kitchen scale
  • sand or rice

Tonight’s 10 minutes

  1. Pour water from different glasses into three identical glasses. Which held the most?
  2. Guess: does this jug hold more or less than 1 litre? Fill from the litre bottle to check.
  3. How many glasses fill the 1 litre bottle? How many bottles fill the bucket?
  4. Lift two bags in turn: which is heavier? Check on the balance.

Words to use

  • litre
  • holds more
  • holds less
  • heavy
  • light
  • balance
  • about

Watch for

  • Thinking a tall glass always holds more. Pour a tall thin glass into a short wide one.
  • Judging weight by size. A small bag of rice can outweigh a big bag of cotton. Lift both.

What it sounds like at home

A short example of the conversation. Your words will differ; the questions are what matter.

YouWhich glass has more milk?

Your childThe tall one.

YouPour both into same glasses.

Your childThe short one had more!

YouWhy?

Your childIt’s wider.

A game for this week: Litre guess

  1. Line up five containers.
  2. Guess: more than, less than or about 1 litre?
  3. Check by filling from a 1 litre bottle.
  4. Score a point for each right guess.

A 5-day plan, 10 minutes a day

  1. Day 1Pour to compare glasses.
  2. Day 21 litre bottle as a unit.
  3. Day 3Glasses to fill a bottle.
  4. Day 4Heavier or lighter by lifting.
  5. Day 5Litre guess game.

Everyday moments to practise

  • Milk packets of 500 ml and 1 litre.
  • Filling a bucket for bathing.
  • Carrying shopping bags.
  • Weighing vegetables at a shop.

Quick check

Ask these at the end of the week. Tap to see the answer.

Does a bucket hold more or less than 1 litre?

More.

How can you check which glass holds more?

Pour each into identical glasses and compare.

Which is heavier: a pillow or a 1 litre bottle of water?

Usually the water bottle; test it.

Ready for the next chapter when your child…

  • Compares capacity by pouring.
  • Says more or less than 1 litre.
  • Compares weights by lifting and on a balance.

Questions parents ask

What is capacity?

How much a container can hold.

How much is 1 litre?

Is weight measured in kg in Class 3?

The chapter focuses on comparing heavy and light; kilograms come more in Class 4.
