To compare two four-digit numbers, look at their digits from left to right. Start with the thousands digit, since it carries the most value. **Example.** The Otters counted 4,582 bottle caps. The Herons counted 4,519. The thousands digits are both 4, so that is a tie. The hundreds digits are both 5, another tie. Now check the tens digit: 8 is bigger than 1. So the Otters have more bottle caps. 4,582 is bigger than 4,519. *(drawing: The number closest to zero is smallest. The number farthest away is biggest.)* **Tip.** If two numbers have a different number of digits, the one with more digits is always bigger. When both have four digits, compare place by place from the thousands down, and stop as soon as you find a difference. **Recap.** Compare four-digit numbers by checking digits from the thousands down, and stop as soon as one digit wins. ## Practice 18 questions on this page, each with its working shown. ## Needs first - [Ordering Numbers to 1000](https://lightmysky.com/learn/mathematics/ordering-numbers-to-1000-mt_AQcVRBddko) - [Numbers to 10,000](https://lightmysky.com/learn/mathematics/numbers-to-10-000-mt_lC_Q5mSL_I) ## Opens up - [Place Value Problem-Solving](https://lightmysky.com/learn/mathematics/place-value-problem-solving-mt__sMrmOv3bx) - [Reading and writing numbers (age 9+)](https://lightmysky.com/learn/mathematics/reading-and-writing-numbers-age-9-mt_JwP9QFv6gQ)
