There are 15 different 2 digit regrouping timed tests with both subtraction and addition. I give my students (second grade) 2 minutes to complete the tests. Once they pass test #1 they would move onto test #2 until they have completed all of 15 of them. You can reward students for passing their tests and chart their progress. This is a fun way to practice basic operations with regrouping everyday.
