FAQ
When adding a 1-digit number to a 3-digit number, which column do students start with?⌄
Students begin with the ones column, just as in any column addition problem — if the ones digits sum to 10 or more, they regroup (carry) into the tens column.
How do these problems build on 2-digit addition skills?⌄
The process is identical to 2-digit addition, but students must track the hundreds place as well, reinforcing that multi-digit addition follows consistent column-by-column rules.
Are regrouping skills required for all problems in this set?⌄
Not always — some problems have ones digits that sum to less than 10, so students get practice both with and without carrying, building well-rounded addition fluency.
