These tips are from a site I found on the Internet.
Middle School students are busier people. They will also start to see long-range assignments that require more organization and planning - skills that will be crucial in high school. Here are some tips that can help with this transition.
Organize First - Encourage your child to plan each evening's studying carefully. Tackle assignments due tomorrow first. Then work on the project due next Monday. An assignment book is essential.
Special Supplies - Each afternoon, ask whether tonight's assignments require special books or supplies. Make that trip to the library or hardware store early!
Offer feedback - Encourage your child, but don't offer answers. Questions like, "Does that answer look correct to you?" will help your child without doing her work for her.
Don't procrastinate - Leaving a large assignment until the last minute can be tempting. Push hard to encourage your child to start projects early.
Enforce a routine - Middle schoolers have more distractions, activities, and friends. Remind them that these are all important, but homework is essential. Homework first; friends, computers, and hobbies later.
Take it with you! - Middle school students have LOTS of distractions. Encourage your child to be sure everything is packed up for tomorrow before he goes to bed.
