Class 4 Maths - ANDHRA-PRADESH
Thousands Around Us
In the Class 4 Mathematics chapter 'Thousands Around Us' under the Andhra Pradesh (BSEAP) syllabus, students step into the world of four-digit numbers. This chapter builds upon the three-digit numbers learned in Class 3, teaching children how to read, write, and understand numbers up to 9,999. Students explore place value, face value, expanded forms, and how to compare large numbers. This foundational knowledge is crucial for board exams as it forms the basis for all future arithmetic operations like addition, subtraction, multiplication, and division involving larger quantities in daily life.

Four-Digit Numbers
Numbers that have four digits, starting from 1,000 (one thousand) and ending at 9,999 (nine thousand nine hundred ninety-nine).
Place Value and Face Value
Face value is the actual digit itself, while place value depends on the digit's position (Ones, Tens, Hundreds, or Thousands) in the number.
Expanded Form
Writing a number by showing the value of each digit according to its place, such as 4,523 = 4,000 + 500 + 20 + 3.
Comparing Numbers
A method to find out which number is greater or smaller by first comparing the thousands digit, then hundreds, tens, and ones.
Predecessor and Successor
The predecessor is one less than a number (minus 1), and the successor is one more than a number (plus 1).

Frequently Asked Questions
How do we read a four-digit number?
We read a four-digit number by starting from the thousands place, followed by the hundreds place, and then reading the last two digits together as a tens-and-ones number.
What is the difference between place value and face value?
Face value never changes and is the digit itself. Place value changes depending on where the digit is placed in the number (e.g., in 4,523, the face value of 5 is 5, but its place value is 500).
What is the smallest four-digit number?
The smallest four-digit number is 1,000, which comes right after the largest three-digit number, 999.
