As long as my kids have been in grade school, we’ve done math drills almost every school night of the year. You’d think they would get enough math practice after a few weeks… but then again, I guess that until they have their single-digit addition skills memorized, math worksheets are a bit of a chore.
These addition practice worksheets are restricted to single digits and have 100 sums on each page. This way you can use them for math practice as well as timed math drills.
