What Are Large Numbers?
Large numbers are numbers that are bigger than what we use every day, like 10, 100, or 1,000. They help us count many things, like people, stars, or money!
Reading Large Numbers
Large numbers have many digits. We group digits in sets of three, starting from the right, to read them easily.

| 1,234 | 1, 234 | One Thousand Two Hundred Thirty-Four |
| 56,789 | 56, 789 | Fifty-Six Thousand Seven Hundred Eighty-Nine |
| 1,234,567 | 1, 234, 567 | One Million Two Hundred Thirty-Four Thousand Five Hundred Sixty-Seven |
