Math Lesson Structure

It's been two weeks since school has started.  This year in fifth grade we have homogeneous groups created by the fourth grade team.  Because of this, I have had to come up with a new Math routine/structure.  I want to take advantage of every minute I have them for instruction, particularly because fifth graders have significantly less time for instruction than they do in fourth grade.  In fourth grade they had two hours, including enrichment.  In fifth it is down to one hour and fifteen minutes.
10:00-10:15:  Agendas, Homework, and Fact Folders
Students trickle in from the other five fifth grades (no bells at our school) and get out their Agendas with homework on top.  This allows me to quickly check in homework and write in their agendas.  They copy down the homework for the next day (which is already on their desks).  After that, they set up their Math fact folders which is a blank worksheet under a clear sheet of plastic which they write on with a dry erase marker.  Each child is on a different level of multiplication facts.  This takes the most time, since they aren't used to creating their fact sheet and monitoring themselves.  I hope this will take less time as the year progresses.  If students finish all of this, they may start on their homework.  I was going to have some type of Daily Math or Problem of the Day, but why go through the trouble of finding and copying all of that when they could start their homework?
10:15-10:30:  Mini-Lesson:  Review or Introducing a New Concept
As my aide goes around to check their fact folders, I take the kids to the carpet to do a review activity.  Often we use personal whiteboards that are in a basket in the middle of the carpet.  
10:30-10:15:  Back to Desks:  Main Lesson
Students come back to their desks and check the status of their Fact Folders.  If they passed a level, they record it on the chart in the folder.  This process is taking about five to ten minutes now.  I hope we can cut this down significantly in the coming weeks.
This is where and when I deliver the main content of the lesson.  I am making good use of the students' interactive Math notebooks.  After some challenges getting started (again, this class has difficulties following multi-step routines/directions) the students are already really enjoying them.  Each Monday night's homework will be creating their weekly student reflection page in the notebook.  Since their journals are so small (composition books cut in half) I decided to do this instead of the traditional left side-right side organizational structure.  These journals are so new for them I don't want to overwhelm them with coming up with multiple pages.  We usually fill one page a day in class.
