It would be the best if the child, after a short break, immediately learns all the lessons and do the homework from the present school day. Follow the course of learning, find out how much she remembers from the school and go through hers notes. Do not let her sit too long over the book, encourage her to be focused, limit the time for each subject, if necessary. If your child doesn’t understand something, ask her to read you that part of the book, and then say how she understood it. Ask her questions, and let her arrive to conclusions on hers own. You should never read and present the complete solution.
Your help will be less needed and she will begin to study on her own.
Then the child should revise the lesson for the next school day. Then, pack the books, notebooks and material for tomorrow.
Spend the rest of the day without talking about school work.
