About this topic
The number 5 is a fantastic number! 🎉It comes right after 4 and before 6 in the number line. When you count, you say "1, 2, 3, 4, 5." In math, 5 is also called an odd number because it cannot be divided evenly by 2 (2 goes into 5 two times with 1 leftover). We use the number 5 in many ways, such as counting fingers on one hand. 👋Did you know that 5 is also the number of continents in the world: Asia, Africa, North America, South America, and Europe? 🌍
