Many years ago, in the Village ‘Of Jadupur’, people exchanged things based on their needs. Shaamu Kaka gave 5 sacks of rice to Dariya Didi. She in return gave 10 sacks of vegetables. Dariya Didi got 2 sarees from Bablu Dada by giving 5 sacks of onions.

Like this, people in the village exchanged their things. Shamu Kaka got vegetables for the rice he gave. Dariya Didi gave lots of onions to Bablu Dada for the two sarees. Discuss in class why people in this village had to give different quantities while exchanging things.

These days we use money in exchange for things we need. Notes and coins come in different values which are used to buy different things.

For example, one 10-rupee note can buy one Hawa Mithai or ten toffees.

One Hawa Mithai costs more than a toffee. Salma buys two bottles of milk for **₹** 100. Kiran buys a basket of pomegranates for **₹** 100.

Circle the one that costs more: a milk bottle or a pomegranate?

Think of two things that we can buy using the same note.

**Match the notes and coins in the two columns that have the same values.**

**Use the following notes and coins to buy the things given below. Find at least two ways of giving the money. You may use the notes and coins more than once.**

In the morning, Peter’s uncle has ₹ 465 in his money box. By afternoon, he has **₹** 756. How much has he earned since morning?

Today, Peter’s uncle sold rice for **₹** 640 and sugar for ₹ 215. How much money has he earned from this sale?

**Let us do**

**Solve the following problems using box diagrams. Estimate the answers. Then use notes of ₹ 100s, ₹ 10s, and ₹ 1s or a number line to solve the problems.**
