FAQ
Why is correct column alignment especially important in 2-digit plus 1-digit column addition?⌄
The 1-digit addend must be placed in the ones column beneath the ones digit of the 2-digit number; misalignment causes the digit to be incorrectly added to the tens place.
Should students set up their own columns from horizontal problems, or are columns pre-formatted?⌄
Both formats are valuable — pre-formatted columns build algorithm fluency while converting horizontal problems to columns develops the organizational skill students need on open-ended assessments.
What does a 2-digit plus 1-digit column problem look like when regrouping is required?⌄
If the ones digits sum to 10 or more, students write the ones of the result below the ones column and carry the 1 above the tens column of the 2-digit addend before adding tens.
