How Heavy? How Light?

How much does a postcard cost?

How much does an inland letter cost?

Father gave them some idea of the weight of each thing.

Find out the total weight they had loaded on the cart.

Which things should be removed so that the weight of the load is not more than 700 kg?

Now, you also make your own balance. Write down how you made it. Also draw a picture of your balance in the box below.

Mannu and Jaiju put a pencil and geometry box in the two pans of the balance. Which pan will go down? Why? Draw a picture to show it.

Make pairs of different things and use the balance to decide which is heavier. First guess which thing will take the pan down and then check with your balance.

Make groups of three things. For example - eraser, ball and paper. Use the balance to arrange them in order of weight-the lightest, the one with in-between weight, the heaviest.

Complete the table with at least five examples.
