When your children are doing their homework, limit the noise in the house as much as possible. They will be able to concentrate better without distractions. For the rest of the summer, set aside time each day when your kids can work on academic skills, such as reading, math, and journal writing. Once school starts, this can become their homework time. Although you may have to make some changes due to lessons, classes or practices, try to stick to the same basic schedule as much as possible.
Kids respond well to structure and schedules, so try to be consistent from the beginning.
Aside from nightly assignments, your children should probably spend some time practicing skills each day. Create a checklist for each child that indicates which skills should be worked on each day. Spending a few minutes on spelling words and math facts can increase your child's ability to recall them, and will probably help his overall grades, too. Daily reading practice is also important. They need to know what is expected of them and how they can go about meeting those goals.
