Measuring Weight  "Heavy or Light?"  
Let's Practice 
Once upon a time, in Maya's house, there was a special juice party. Rita, Monu, and Niti gathered around the table, each with their own glass of juice.
After they happily drank their milk, Rita's clever sister had an idea. She poured the milk from each glass into three identical glasses. What a surprise! Even though the glasses looked the same, they didn't all hold the same amount of milk!
Imagine you have a big bottle of juice.
The amount of juice it can hold is measured in litres, written as "L". But if you look closely at a bottle of medicine or a juice box, you might see a number followed by "mL". That stands for millilitres, which is a smaller unit of measurement.
 1 litre is the same as 1000 millilitres! So, if you have a litre of juice, that's like having 1000 tiny millilitres.
 To understand how small a millilitre is, think about a teaspoon. It can hold about 5 millilitres of liquid.

And a tablespoon can hold about 10 millilitres!

The standard sized containers used for measuring liquids are shown.
So, next time you see a jug marked with litres or a bottle with millilitres, you'll know exactly how much liquid it can hold. It's like solving a fun puzzle about liquids!
To understand more than and less than in terms of volume or capacity, think about it like this:
Imagine you have two containers, one labeled A and the other labeled B. Let's say container A can hold 500 milliliters (ml) of water, and container B can hold 750 ml of water.
Now, let's reverse the situation. Suppose container A can hold 1 liter of water (1000 ml), and container B can hold 750 ml of water.
These concepts help us compare the capacity of different containers or quantities of liquid, which is important in many everyday activities like cooking, measuring drinks, or understanding the size of containers.
Imagine Chintu holding three heavy textbooks, each weighing 1 kilogram, and a light pencil box weighing 500 grams. His hand with the textbooks goes lower because they're heavier. This is how we can compare things like to see which is heavier or lighter.Long ago, people didn't have fancy scales to measure the weights of things, like today. They used rocks or stones to measure weight! They added or took away rocks until things balanced 0.
But now, we have grams and kilograms.
Please note that, 1 kilogram = 1000 grams.
Some standard weights are given as follows:
1. Look at the picture and tick the appropriate word.
(a) The mug holds a litre/half litre water.
(b) The glass holds a litre/half litre/quarter litre of water.

2. Can you guess which of these things might weigh more or less than 1 kilogram? Put a check mark (✔️) in the right box.

To understand more than and less than in terms of weight or mass, think about it like this:
These concepts help us compare the weights of different objects, which is important in various activities like measuring ingredients in cooking, comparing the weight of items in a store, or understanding the capacity of different vehicles to carry weight.
Imagine you have two objects, one object A and another object B. Let's say object A weighs 500 grams, and object B weighs 750 grams.
Now, let's reverse the situation. Suppose object A weighs 1 kilogram (1000 grams), and object B weighs 750 grams.
