Exploring the Addition of 3-Digit Numbers

Explanation:

To find two possible addends where one has an 8 in the tens place and the other has a 1 in the tens place, we can start with two 3-digit numbers. Let's say one number is 800 and the other is 100. When we add these numbers, Dylan would regroup the tens as hundreds, resulting in the sum of 900.

Another set of possible addends could be 850 and 150. Again, when we add these numbers, Dylan would regroup the tens as hundreds, resulting in the sum of 1,000.

It is essential for Dylan to understand how to regroup tens as hundreds when adding 3-digit numbers to prevent errors in the calculations.

Practicing addition with different sets of addends that require regrouping can help Dylan become more proficient in arithmetic and enhance his mathematical skills.

Understanding regrouping in addition is crucial for accurate computation and building a strong foundation in mathematics.
