scrimmages

In my district, we have certain standards we are required to teach for a 3 week period.  We then test the students over those standards.  There are 2-3 questions per standard for a total of 6 questions per test.  We have to then rank the students by percentages- either intervention, strategic, and passing.  Then, for the next 3 weeks, we reteach to the intervention and strategic students the standards that they didn't get.  We only have a 1/2 hour a day to reteach.  3 days a week are language arts and 2 days are math.  I am really struggling with my kids in math.  I wish my principal would let me do 3 days of math and 2 of language arts.  Does anybody else do this kind of testing or reteaching?  Any hints?
