You already know how to count by 2s, and you know the hundreds: 100, 200, 300. Now you will count all the way to 1,000, one at a time, by 5s, and by 100s. *(drawing: Each jump adds 5. Count the jumps: 5, 10, 15, 20, 25, 30.)* **Example.** Ben has 4 boxes with 100 blocks in each box. He skip-counts the boxes instead of counting every block: 100, 200, 300, 400. He already knows the hundreds, so counting on is fast. **Tip.** Counting backward works the same way, just take away instead of add. From 400, subtract 100 each time: 400, 300, 200, 100, 0. If you lose your place, say the forward pattern first, then read it backward. **Recap.** You can count forward or backward, by ones, by fives, or by hundreds, all the way to 1,000. ## Practice 17 questions on this page, each with its working shown. ## Needs first - [Counting in 2s, 5s and 10s](https://lightmysky.com/learn/mathematics/counting-in-2s-5s-and-10s-mt_nvdpxAJTBG) - [The multiples of 100](https://lightmysky.com/learn/mathematics/the-multiples-of-100-mt_R2ccrI-nKD) ## Opens up - [Negative Numbers](https://lightmysky.com/learn/mathematics/negative-numbers-mt_vXRzMbiPff)
