NCERT Solutions for Class 4th Maths Chapter 4 Thousands Around Us
Updated on 2026-09-19
About this chapter
10 Ones = 1 Ten, 10 Tens = 1 Hundred, and 10 Hundreds = 1 Thousand (1000). The Indian place value chart for this class has four columns: Th, H, T and O. A four-digit number is read Thousands first, then Hundreds, then Tens, then Ones. Expanded form splits a number by place: 3452 = 3000 + 400 + 50 + 2. The digit 0 is a place holder — it keeps the other digits in their own places, as in 4085. To compare two numbers, start at the Thousands place and move right until the digits differ.

Quick revision
| Idea | What it means | Example | Remember |
|---|---|---|---|
| 10 Ones | 1 Ten | 10 Ones = 10 | One rod of ten |
| 10 Tens | 1 Hundred | 10 Tens = 100 | One flat of hundred |
| 10 Hundreds | 1 Thousand | 10 Hundreds = 1000 | One big cube |
| Place value chart | Th, H, T, O | 1005 → 1, 0, 0, 5 | Read left to right |
| Expanded form | Value of each digit added | 1402 = 1000 + 400 + 0 + 2 | Zero adds nothing |
| Number name | The number in words | 3019 = three thousand nineteen | Thousands first |
| Regrouping | Ten small make one big | 15 Tens = 1 Hundred + 5 Tens | Group in tens |
| Comparing | Check Th, then H, then T, then O | 3012 < 3102 | First unequal digit decides |
| Smallest 4-digit number | 1000 | 999 + 1 = 1000 | Just after 999 |
| Largest 4-digit number | 9999 | 9997, 9998, 9999 — then stop | Class 4 stops at 9999 |
