                                    LN- Reading and Writing 3-digit and 4-digit Numbers
               Learning Objectives:


                   •  Read and write 3-digit and 4-digit numbers correctly.
                   •  Understand the place value of digits in these numbers.


                   •  Write numbers in Composed form, word, and Decomposed form.



               1. Understanding Place Value:
               Each digit in a number has a place value depending on its position.

               Place Value Chart:

               Thousands                Hundreds               Tens         Ones


               1,000                    100                    10           1



               Example:
               4372
                   •  4 is in the Thousands place → 4000

                   •  3 is in the Hundreds place → 300

                   •  7 is in the Tens place → 70

                   •  2 is in the Ones place → 2



               2. Reading and Writing Numbers

               A. Composed Form

               This is the usual way we write numbers using digits.
               Example: 638, 1204

               B. Word Form

               We write the number in words.
               Examples:
