Subject: subtraction with regrouping
I teach the kids to begin in the ones place and put a dot next to the greater number. If the greater number is on the bottom, then we regroup. If it is on the top, we subtract like normal. This is a great visual cue when they don't have manipulatives on the standardized test.
