What's in a Name? — Class 3 Mathematics (CBSE)
From the current NCERT Maths Mela Grade 3 book, Chapter 1. A gentle start to data handling: children use the letters in names to count, compare, sort, and show information clearly.
1. Why this chapter matters
Maths is not only about big sums. It also helps us collect information and make sense of it. In this chapter, your own name and your friends' names become the data. You count letters, compare names, and show what you find in a neat table or picture. This builds careful counting, comparing, and the habit of organising information — skills used all through maths.
2. Core ideas
Idea 1 — Data is information we collect
The number of letters in a name is a piece of data. For example, RAM has 3 letters and SUNITA has 6 letters.
Method 2 — Count, then compare
Count carefully, then use words like more, less, longest, shortest, equal. SUNITA (6) is longer than RAM (3).
Skill 3 — Show data neatly
Put your data in a table or a picture graph (pictograph) so it is easy to read and compare.
3. Worked examples
Example 1: How many letters are in the name MEENA?
Count each letter: M-E-E-N-A → 5 letters.
Example 2: Whose name is longer, ASHA or KARTIK?
ASHA has 4 letters; KARTIK has 6 letters. KARTIK is longer, by 6 − 4 = 2 letters.
Example 3: Make a table for three friends.
| Name | Number of letters |
|---|---|
| RAM | 3 |
| MEENA | 5 |
| KARTIK | 6 |
| The shortest name is RAM; the longest name is KARTIK. |
4. Activity corner
Write the names of 5 family members. Count the letters in each. Then answer:
- What I observed (which name is longest / shortest)
- What I counted or compared
- What maths idea this shows (collecting and comparing data)
5. Common mistakes
- Mistake: Counting a letter twice or skipping one. Fix: Touch each letter once as you count, left to right.
- Mistake: Saying "bigger name" without counting. Fix: Always count the letters first, then compare the numbers.
- Mistake: Messy lists that are hard to read. Fix: Use a neat table with a heading for each column.
6. How to write better answers
- Write the names you are comparing.
- Count and write the number of letters for each.
- Compare using more, less, longest, or shortest.
- Write the final answer in a complete sentence.
7. Practice set
- How many letters are in the name GEETA?
- Whose name is longer: AMIT or PRIYA?
- Write the shortest name: OM, RANI, DEEPAK.
- Make a table of letter-counts for: SARA, JOHN, ANANYA.
- How many more letters does ANANYA have than SARA?
- Why is it helpful to put name data in a table?
8. Answer key
- GEETA has 5 letters.
- AMIT (4) and PRIYA (5) → PRIYA is longer.
- OM (2 letters) is the shortest.
- SARA = 4, JOHN = 4, ANANYA = 6.
- ANANYA (6) − SARA (4) = 2 more letters.
- A table makes the data neat and easy to compare at a glance.
9. Quick revision
- Data is information we collect, like the number of letters in a name.
- Count carefully, then compare using more, less, longest, shortest.
- Show data in a table or a picture graph.
- Always count before you compare.
- Maths Mela Chapter 1 starts data handling in a fun way.
