Add Two Digit Numbers Without Regrouping Practice Worksheets
Learning to add two-digit numbers without regrouping is a fundamental math skill that requires practice and patience. In this article, we will provide you with practice worksheets and tips to help you master this skill.
What is Regrouping in Math?
Regrouping in math refers to the process of carrying over a digit from one place value to the next when the sum of two numbers exceeds the value of the current place value. For example, when adding 45 + 27, the sum of the tens place (4 + 2) is 6, and the sum of the ones place (5 + 7) is 12. To write the correct answer, we need to regroup the 1 from the ones place to the tens place, making the correct answer 72.
Why Practice Adding Two Digit Numbers Without Regrouping?
Practicing adding two-digit numbers without regrouping helps build a strong foundation in math and prepares you for more complex math operations. By mastering this skill, you will be able to:
- Develop mental math skills and estimate sums quickly
- Improve your accuracy and speed in math calculations
- Build confidence in your math abilities
- Prepare for more complex math operations, such as regrouping and multi-digit addition

What is the difference between regrouping and non-regrouping addition?
+Regrouping addition involves carrying over a digit from one place value to the next when the sum of two numbers exceeds the value of the current place value. Non-regrouping addition, on the other hand, does not involve carrying over digits.
Why is it important to practice adding two-digit numbers without regrouping?
+Practicing adding two-digit numbers without regrouping helps build a strong foundation in math and prepares you for more complex math operations. It also develops mental math skills and improves accuracy and speed in math calculations.
How can I use mental math tricks to add two-digit numbers without regrouping?
+One mental math trick is to use the “nines trick”, where you add 9 to the first number and subtract 1 from the second number. For example, 14 + 25 = 14 + (20 + 5) = 14 + 20 + 5 = 39.
