Halves (Grade 2)
Half means dividing something into 2 equal parts and taking one part. The word for half is written as 1/2 (one out of two equal parts).
In Class 2, you learn to find half of shapes, objects, and small numbers.
What is Halves (Grade 2) - Class 2 Maths (Fractions Introduction)?
When we divide something into 2 equal parts, each part is called a half. The fraction for half is written as:
1/2
The top number (1) means we take one part. The bottom number (2) means the whole is divided into two equal parts.
Important: The two parts must be equal. If the parts are not equal, they are not halves.
Halves (Grade 2) Formula
Half of a number = Number ÷ 2
Solved Examples
Example 1: Half of a Shape
Question: A circle is divided into 2 equal parts. What is each part called?
Think:
- The circle is divided into 2 equal parts
- Each part is one out of two = 1/2
Answer: Each part is called a half (1/2).
Example 2: Half of a Number
Question: What is half of 10?
Think:
- Half of 10 = 10 ÷ 2 = 5
Answer: Half of 10 is 5.
Example 3: Word Problem — Sharing Chapatis
Question: Ria has 8 chapatis. She gives half to her brother. How many does she give?
Think:
- Half of 8 = 8 ÷ 2 = 4
Answer: Ria gives 4 chapatis to her brother.
Example 4: Is This a Half?
Question: A rectangle is divided into 2 parts, but one part is bigger than the other. Is each part a half?
Think:
- The two parts are NOT equal
- For halves, both parts must be the same size
Answer: No, these are not halves because the parts are not equal.
Example 5: Word Problem — Sharing Mangoes
Question: Dev and Kavi share 14 mangoes equally. How many does each boy get?
Think:
- Half of 14 = 14 ÷ 2 = 7
Answer: Each boy gets 7 mangoes.
Example 6: Half of a Larger Number

- Half of 20 = 20 ÷ 2 = 10
Answer: Half of 20 is 10.
Example 7: Doubling and Halving Connection
Question: Double of 6 is 12. What is half of 12?
Think:
- Doubling and halving are opposite
- If 6 + 6 = 12, then half of 12 = 6
Answer: Half of 12 = 6
Key Points to Remember

Frequently Asked Questions
Q1. What is a half?
A half is one of two equal parts of a whole. It is written as the fraction 1/2.
Q2. How do you find half of a number?
Divide the number by 2. For example, half of 10 = 10 ÷ 2 = 5.
Q3. Can any shape be divided into halves?
Yes, any shape can be divided into halves as long as the two parts are exactly equal in size.
Q4. What is the connection between doubles and halves?
They are opposite operations. If double of 7 is 14, then half of 14 is 7.
Q5. Is half of an odd number a whole number?
No. Half of an odd number like 7 is 3.5, which is not a whole number. In Class 2, we mostly find halves of even numbers.
Q6. What does 1/2 mean?
The top number 1 means we take one part. The bottom number 2 means the whole is split into 2 equal parts. So 1/2 means one out of two equal parts.
Q7. If I cut a roti into 2 parts but they are not equal, is each piece a half?
No. For each piece to be called a half, both pieces must be the same size. Unequal parts are not halves.
