Tens are numbers that are multiples of 10, such as 10, 20, 30, and so on up to 100. Understanding tens is an essential foundation for calculations with two-digit numbers. By working with tens, children learn to navigate the number range confidently and understand the structure of the decimal system.

When practicing with tens, students work on counting by 10s as well as quickly adding and subtracting tens. This helps them develop essential strategies, such as working with round numbers and simplifying calculations. Additionally, understanding place values—ones, tens, and hundreds—is reinforced, laying the groundwork for all future math operations.
