Subject: Addition error pattern

As part of a masters in elementary program, I have been assigned the task of
remediating the following addition error pattern: Whenever a column of
addition contains a zero, the student writes a zero in the answer for that
column -

             569
             350
            +323
            ____
            1230

The tens column was missing the regrouped digit because of the error and the
hundreds column was added correctly.

What strategies can you suggest to help remediate this error pattern?

Thank you,
