How in the world do you keep everything graded and have the lesson plans all lined up? I homeschool four of my five kids ranging in age from 9 up to 18. I cannot keep up with the lesson plans and grading. Thank goodness the two oldest have a structured online curriculum but the two younger ones do not. I am finding it very hard to keep up. How do you all do it?I'm lucky if I get in bed before 2 every night. I welcome any suggestions.
