Answer:

To determine if the addition problems require regrouping (carrying), we need to add the numbers and see if any column sums to a value greater than 9. If any column's sum exceeds 9, we need to regroup.

1. **456 + 278 + 341**

- Units: 6 + 8 + 1 = 15 (Regroup needed)

- Tens: 5 + 7 + 4 = 16 (Regroup needed)

- Hundreds: 4 + 2 + 3 = 9 (No regrouping needed)

- **Regroup**

2. **789 + 123 + 366**

- Units: 9 + 3 + 6 = 18 (Regroup needed)

- Tens: 8 + 2 + 6 = 16 (Regroup needed)

- Hundreds: 7 + 1 + 3 = 11 (Regroup needed)

- **Regroup**

3. **523 + 287 + 491**

- Units: 3 + 7 + 1 = 11 (Regroup needed)

- Tens: 2 + 8 + 9 = 19 (Regroup needed)

- Hundreds: 5 + 2 + 4 = 11 (Regroup needed)

- **Regroup**

So, the answers to write on your drill board are:

1. Regroup

2. Regroup

3. Regroup
