Problem: Article: If you've gone through your bag and removed all of the clutter, you'll likely have gotten rid of books or items you don't need. To tell if an item is unnecessary, think about whether you use it frequently or at all. If you use it daily, keep it in the bag. If you haven't seen it in weeks, take it out. Make decluttering a habit! If you know you won't need something, leave it out of your bag. Go through your bag weekly to make sure you haven't piled up more of the same old things. If there are certain things that you know you won't need at home, leave them in your locker. This includes extra notebooks, textbooks for classes without homework that night, sports supplies, etc. Go through your class schedule and see exactly what you will need to take with you for the next day. This will ensure that you're not carrying unnecessary books, notebooks or supplies. Here, unnecessary supplies are ones that you won't specifically need tomorrow. If you have Algebra, History and Spanish, leave out your English and Biology notebooks and texts. While big binders and multiple-subject notebooks are great for organization, they also add a lot of weight, especially when they contain notes for classes you don't need every day. Invest in supplies that will help you separate your carry load and lighten your pack.  Get separate notebooks for each class. If you have one small notebook for each subject or project, you'll be able to carry only what you need for each day, leaving behind the notebooks you definitely won't need. Get notebooks in different colors if you have a hard time keeping them all straight. Invest in compact notebooks. A4 is the standard paper size for most notebooks, but it includes a lot of margin room. All of that extra space on the paper adds up in weight, and you may not even get to the end of the notebook! Look at smaller A5 or even A6 notepads to cut down on the size and weight of your notebooks.  Carry travel sized items. If you frequently carry hairspray, lotion or other grooming products for use after gym, buy smaller sizes. Liquids weigh a lot and that weight adds up. If your favorite products don't come in travel sizes, buy small plastic bottles and transfer your products into them. Try sites like Amazon or The Container Store for small bottles. The less papers and books you have to carry, the lighter your backpack will be. Some textbooks come in electronic format, and you may be able to scan your homework and turn it in online. Also, consider scanning your book chapters and keeping them in digital form if an eBook is not available with the bound edition.This way, you'll only have to carry a laptop or tablet instead of books and papers. While it may be hard to remember to do this, giving your parents any notes or letters means less weight in your backpack. Letters and notices tend to pile up especially if you're forgetful about them. The sooner you do homework, the less likely it is to get lost or be forgotten in your bag, turning into dead weight. Also, when you finish the homework, you'll no longer have to carry the corresponding textbook to and from school, saving your bag 20 or 30 pounds. Going through your bag weekly will help cut down on the clutter and the weight of the bag. It will also give you a good time to re-organize things back into the pockets they belong in, keeping the distribution of weight correct.
Summary: Don't keep unnecessary things in your bag. Store items in your locker. Plan your day the night before. Buy smaller versions of what you have. Go electronic if your school will let you. Give parents notes and packets as soon as you get them. Don't procrastinate on your homework. Clean your bag out weekly.

Problem: Article: To get a better idea of how the course content will unfurl over the course of the term, read through the main course materials as outlined in last year’s syllabus or scheme of work. If there is a specific textbook associated with the subject that you’re teaching (e.g. mathematics), review it and take note of how much focus is allotted for different topics. Complete your scheme of work accordingly. For instance, two chapters might be devoted to polynomial functions, while differential equations might only be covered in one chapter. If multiple course materials are assigned for a course, decide how much time and academic focus each should be allotted. For example, if various novels or plays are assigned in an English course, give each a sufficient measure of focus. If you add or remove course content, make sure that there is an appropriate amount of reading for each week. Before planning and detailing your scheme of work, get information about the curriculum requirements in place at your institution. For instance, students might have to master a certain set of skills in an introductory course to be prepared for a more advanced course the following year. Ask the school administration, or review the previous instructor’s work and materials to get a better idea of what constraints might be in place. In addition, look into whether the class could benefit from new course materials and updated unit plans of learning. Based on the course materials and grade requirements, write a list of learning objectives for each individual unit and for the course as a whole. Adjust and edit these objectives as you work out time constraints and actionable learning activities, to ensure that you add well-thought out goals to your scheme of work. Make sure that each objective follows the S.M.A.R.T. acronym:  Specific Measurable Attainable/achievable Realistic Time-bound Schemes of work are working documents, so you can always collaborate with students or colleagues and adjust the document after the initial copy is produced. This offers the opportunity for you to confer with students about upcoming learning activities and goals, and modify them accordingly. Show students a copy of the first draft of your scheme of work and get their feedback and ideas about how learning should progress. For instance, a teacher may have initially scheduled a brief lecture and note-taking for a lesson on the Cold War, but amends the unit plan to schedule a class discussion instead to defer to the preferences of the class.
Summary: Read through the course materials. Divide reading time appropriately. Research your constraints. Set out academic objectives. Collaborate with students.

Problem: Article: Some 4-way switches may have the "in" and "out" pairs opposite each other, rather than top and bottom. Look at the markings on yours and read the instructions carefully. If you are adding more 4-way switches, repeat these steps with the two 3-conductor cables entering each 4-way switch location from the adjacent switches.
Summary:
Attach the red wire entering the 4-way switch box from the first 3-way switch box to the red wire going to the next 4-way switch. Attach the black and white/blue traveler wires entering the 4-way switch box to the "in" terminals, often the top terminals on the 4-way switch - black on the left top pole and white/blue on the right top pole. Attach the black and white/blue traveler wires exiting the 4-way switch box to the next 4-way (or final 3-way) switch box to the "out" terminals, often the bottom terminals on the 4-way switch - black on the left bottom pole and white/blue on the right bottom pole.
