First up: the number 13440 is written as Thirteen Thousand Four Hundred Forty in English (say it like "THUR-teen THOW-zand FOR-tee"). We use these words for awesome things like money, game points, or counting treasures. Writing numbers in words makes them clear and exciting for everyone.

Breaking It Down with a Place Value Chart
The easiest way to write 13440 in words is with a place value chart. Think of it as a pirate map showing where each digit hides. For 13440, we have five digits: 1, 3, 4, 4, and 0. Each has a special spot, starting from the right.
Here’s the chart (picture a vibrant, colorful grid with each box holding a digit):
| Ten Thousands | Thousands | Hundreds | Tens | Ones |
| 1 | 3 | 4 | 4 | 0 |
This chart shows the “expanded form,” like unfolding the number. For 13440, it’s: 1 ten thousand + 3 thousands + 4 hundreds + 4 tens + 0 ones. In numbers, that’s 1 × 10000 + 3 × 1000 + 4 × 100 + 4 × 10 + 0 × 1, or 10000 + 3000 + 400 + 40 + 0 = 13440.
To write it in words: “Ten Thousand” for the 10000, “Three Thousand” for the 3000, “Four Hundred” for the 400, “Forty” for the 40, and skip the zero since it adds nothing. Combine the thousands (10 + 3 = 13, so “Thirteen Thousand”) and add “Four Hundred Forty.” Put it together: Thirteen Thousand Four Hundred Forty! Easy, right?
A Simpler Way to Understand
If charts feel a bit puzzling, try this: start from the left. The 1 and 3 together form 13 in the ten thousands and thousands places, so that’s “Thirteen Thousand.” The 4 in the hundreds place is “Four Hundred,” and the 4 in the tens place is “Forty.” The last digit, 0, means no ones to add. It’s like saying, “Thirteen Thousand Four Hundred Forty, and that’s it!” Try it with a small number like 44 (“Forty-Four”) to get the hang of it!
A Fun Way to Build the Words
Let’s make it a game, like building a tower:
1 is “One.”
Add a zero for 13: “Thirteen.”
Add another for 130: “One Hundred Thirty.”
Another for 1300: “One Thousand Three Hundred.”
One more for 13000, then add 440 for 13440: “Thirteen Thousand Four Hundred Forty.”
It’s like growing a tree from a tiny sprout! Try this with another number, like your favorite score in a game—it’s so much fun.
