How do I determine a schedule?

Here we are in April.  It can be hard to determine a schedule for the remainder of the school year.  Start with a three or four hour schedule of four classes: Math, Science, English, and History.  I am using books for all four classes.  Here is a Co-op guide for Zoology.  Look at this example.  The goal is a chapter each week.  Apologia's Zoology Notebooking Journal has lessons plans.  Heritage Studies 5 Teacher's Edition has a daily study guide.  Saxon Math 5/4 has a guide at the beginning of the student textbook.  There are 120 lessons.  If you teach 150 days, try a lesson each day.  Some lessons may take two days, others only one.  You will have amble time.  In English, I am using an anthology, a vocabulary workbook, a grammar book, and a variety of novels.  I do reading and vocabulary daily and grammar and essays at least twice each week.  We are working about three hours in the morning.  After lunch, Paul exercises, works on experiments, reads, does chores, completes online work, and plays games.
