Make homework LESS work.

Create a Homework Plan
Luckily, there are several things you can do to make homework less work.
First, be sure you understand the assignment. Write it down in your notebook or day planner if you need to, and don't be afraid to ask questions about what's expected. It's much easier to take a minute to ask the teacher during or after class than to struggle to remember later that night! If you want, you can also ask how long the particular homework assignment should take to complete so you can budget your time.
Second, use any extra time you have in school to work on your homework. Many schools have study halls that are specifically designed to allow students to study or get homework done. It's tempting to hang out with friends during study periods or unstructured time, but the more work you can get done in school, the less you'll have to do that night.
Third, pace yourself. If you don't finish your homework during school, think about how much you have left and what else is going on that day, and then budget your time. Most high-school students have between 1 and 3 hours of homework a night. If it's a heavy homework day and it seems like you've got an assignment in every subject but gym and lunch, you'll need to devote more time to homework. It's a good idea to come up with some kind of homework schedule, especially if you are involved in sports or activities or have an after-school job.
Watch Where You Work
When you settle down to do homework or to study, where do you do it? Parked in front of the TV? In the kitchen, with the sound of dishes being cleared and your brothers and sisters fighting?
These places may have worked when you were younger and your assignments didn't require as much skill and concentration. But now that you're older, a bedroom, study, or any other room where you can get away from noise and distractions is the best place to get homework done. But don't study on your comfy bed — opt for a desk or table that you can set your computer on and is comfortable to work at. It doesn't need to be large, just big enough to spread out your stuff.
Get to Work
When you start your homework, tackle the hardest assignments first. It's tempting to start with the easy stuff to get it out of the way, but you'll have the most energy and focus when you begin, so it's best to use this mental power on the subjects that are most challenging. Later, when you're more tired, you can focus on the simpler things.
If you get stuck on a problem, try to figure it out as best you can — but don't obsess and spend too much time on it because this can mess up your homework schedule for the rest of the night. If you need to, ask an adult or older sibling for help or call or email a classmate for advice. But don't pick someone you'll be up all night chatting with or you'll never get it done!
Take a Break
Most people's attention spans aren't very long, so take some breaks while doing your homework. Sitting for too long without stretching or relaxing will make you less productive than if you stop every so often. Taking a 15-minute break every hour is a good idea for most people. (But if you're really concentrating, wait until it's a good time to stop.)
Once your homework is done, you can check over it if you have extra time. Be sure to put it safely away in your backpack — there's nothing worse than having a completed assignment that you can't find the next morning or that gets ruined by a careless brother or sister. (And no teacher still believes that "chewed by the dog" line — even when it's true!) Now you're free to hang out.
