One important organizational tool a student has is you, the teacher. You're a leader in his life, so he may look to you as a role model. Ensure your classroom is organized and that you're prepared for each class. You can also suggest that he uses a tool that you may even employ: a planner. A planner has a calendar he can use to record when all of his assignments are due. It may even have a section that allows him to write a to-do list and a list all of his classes and what time they begin.
It will be easier for students to stay organized by developing certain habits. Suggest at the beginning of each month or semester that students write down realistic goals for themselves, such as attending every class or studying for at least three hours before every test. They can even break these goals into smaller ones so they're easier to manage. Suggest habits they can develop at home that will help them be ready and organized for school, such as preparing wardrobes, lunches and homework the night before school.
Students need a space of their own in school and at home that's only for doing schoolwork and getting ready for school. This area should be well-lit, quiet, kept clean and have all of the materials needed for school, such as pencils, pens and paper. Speak with your students and ask them about the study space they use at home. If some of your students don't have adequate space, speak with the parents to find a solution. At school, suggest quiet areas that students can use, such as a separate area in your classroom or the library.
You may not think of food and sleep as organizational idea, but they're important tools at a student's disposal. Depending on the age of your students, they should be getting at least eight hours of sleep a night. Good sleeping patterns will keep students alert and energized--two qualities they need to stay attentive to their organizational needs. Encourage students to eat three good meals a day and fruit for snacks. Suggest they avoid junk food, which can eventually lead them to feel tired and lethargic--two qualities that won't help them stay motivated to organization. You can't monitor your students 24 hours a day, however, so try speaking with your students' parents and encourage them to reinforce good food and sleep habits at home.
