## Understanding the Concept

Adding two numbers that are in the tens is often referred to as making one addend the next tens number. This is a common math problem that students in elementary school and beyond need to learn how to do. It is a simple concept, but having a good understanding of the fundamentals is essential to being successful in math. Understanding the concept of making one addend the next tens number can be done by breaking down the problem into smaller pieces.

## Using Place Value

Place value can be used to help students understand the concept of making one addend the next tens number. Place value is the value of each digit depends on its position in the number. With making one addend the next tens number, students can use the place value of each digit to add the numbers together. For example, if the two numbers are 30 and 40, the student can use the place value to add the numbers together using the hundreds, tens and ones. In this example, 3 + 4 = 7, so the sum would be 70.

## Using Mental Math

Another way to approach making one addend the next tens number is by using mental math. Mental math is the process of solving math problems without the use of pencil and paper. This can help students learn how to quickly work through problems. For making one addend the next tens number, students can use their knowledge of place value to add the numbers mentally. For example, if the two numbers are 30 and 40, the student can break down the problem into smaller pieces and add the tens and ones together. This would result in 7 tens, or 70.

## Using a Calculator

Using a calculator is another way students can approach this type of problem. A calculator can be used to quickly add two numbers that are in the tens. This is a great option for students who are struggling with the mental math approach or if they need to check their work. With a calculator, students can simply enter the two numbers and the calculator will display the sum of the two numbers. For example, if the two numbers are 30 and 40, the student can enter 30 + 40 into the calculator and the result will be 70.

## Conclusion

Making one addend the next tens number is a common math problem that students need to learn how to solve. There are several different ways to approach this type of problem, such as using place value, mental math, and a calculator. Understanding the fundamentals of place value and mental math can help students become successful with this type of problem. Using a calculator is a great option for students who are struggling or need to check their work. With the right tools, anyone can learn how to make one addend the next tens number.
