What the chapter is about
This chapter visits a coconut farm, where coconuts grow on tall palms near the sea coast. It mixes nature with maths: counting coconuts, grouping them, and finding their cost.
Coconuts are often counted in groups — for example, in tens or dozens. If one tree gives 40 coconuts and there are 6 trees, the farm gives 6 × 40 = 240 coconuts.
The chapter also shows how farmers use coconut: the water for drinking, the flesh for cooking, the shell for craft, and the leaves for roofs. Nothing is wasted.
Counting in groups saves time and prevents mistakes. Market sellers count in dozens, farmers count in bags, and shopkeepers count in packets. The group you choose should make the total easy to multiply.
What you should learn
Grouping is the secret of this chapter: when numbers are big, group them (tens, dozens) and multiply instead of counting one by one.
Key Terms
- Coconut palm — A tall tree that grows coconuts.
- Dozen — A group of 12.
- Harvest — Collecting ripe crops from trees or fields.
- Coast — Land near the sea.
- Grouping — Counting in equal groups to make big numbers easy.
- Basket — A container used to collect and carry coconuts or fruit.
Remember
- One dozen = 12.
- Total = number of trees × coconuts per tree.
- Grouping makes big counting easy.
- Every part of the coconut is useful.
Exam Tip / Common Mistake
Common mistake: counting coconuts one by one in a big problem. Look for the group size first, then multiply.

Think and try
A farmer packs 20 coconuts in each bag. How many bags for 100 coconuts? Solve it two ways: by dividing, and by counting up in twenties. Which way felt quicker for you?
Practice set — try it yourself
- One tree gives 30 coconuts. How many do 7 trees give?
Hint: Multiply. - How many coconuts are in 5 dozen?
Hint: 1 dozen = 12. - A farmer collects 240 coconuts in bags of 20. How many bags?
Hint: Divide. - If one coconut costs ₹15, what is the cost of 10?
Hint: Multiply. - Name three uses of coconut parts.
Hint: Think about water, flesh, shell.
