Me 'n my classmates would practice by spelling everything we saw.

As for grammar, I *still* have no clue but you won't get into that for awhile and really, it hasn't been a problem. I can practice with you anytime, it would probably be good for me since it looks like I'm not getting any class at all this semester.

These sites should help (although I found some of the signs were different):
