FAQ

Should 4th graders still be practicing 2-digit addition?

Yes — fluency with 2-digit addition is the building block for 3- and 4-digit addition, and any gaps at this level slow down progress with larger numbers.

What is the standard algorithm for adding 2-digit numbers?

Students align digits by place value, add the ones column first (carrying if needed), then add the tens column — a process they extend to larger numbers throughout 4th grade.

How quickly should 4th graders solve 2-digit addition problems?

With practice, students should be able to solve simple 2-digit addition problems in a few seconds each, building the automaticity needed for multi-digit and word problem work.
