Write 1 addition problems. Each addend must be three digits. Write and solve a problem where you do not need to regroup to make a ten or a hundred. Explain why you do not need to regroup.
569 + 187 =
569
+187
-----
756
In this problem, we do not need to regroup because the sum of the ones column (9 + 7) is less than 10, the sum of the tens column (6 + 8) is less than 10, and the sum of the hundreds column (5 + 1) is less than 10. Therefore, no regrouping is necessary to find the sum of 569 + 187.
