Each digit has its own place: thousands, hundreds, tens, and ones. The digit in the thousands place tells you which group of a thousand the number belongs to. 10,000 has five digits. **Example.** Look at 3,452. The 3 is in the thousands place, so this number is in the 3,000s. In expanded form, that's 3,000 + 400 + 50 + 2. *(drawing: 3,452 sits between the 3,000 and 4,000 marks, close to the 3,000 side since 452 is a small part of the next thousand.)* To place a number on a 0 to 10,000 line, look at the thousands digit first. It tells you which thousand-sized space to land in. Then use the rest of the digits to nudge closer to one end or the other. **Recap.** The thousands digit shows which group of 1,000 a number belongs to, and the other digits fine-tune exactly where it falls. ## Practice 17 questions on this page, each with its working shown. ## Needs first - [Place Value to 1000](https://lightmysky.com/learn/mathematics/place-value-to-1000-mt_98c2qwEF7Q) - [Representing Numbers](https://lightmysky.com/learn/mathematics/representing-numbers-mt_9L3NQqgqRd) - [Place value of each digit](https://lightmysky.com/learn/mathematics/place-value-of-each-digit-mt_jY7uf0Cb7o) ## Opens up - [Comparing Large Numbers](https://lightmysky.com/learn/mathematics/comparing-large-numbers-mt_MHaiUd2FLA)
