Picture yourself in your bedroom. There is a bed, a desk, and an exercise ball in the room, and there's a mat on the floor. When you do your homework, it doesn't matter which way you sit or lie because you will probably get uncomfortable if you stay in the same position for too long. Can you think of some comfortable positions you can sit and lie in as you finish your homework?

Positions you can sit and lie in could include:

Some accessories can make you more comfortable when you do your homework, so you'll work better. These include:

A left-hand mouse. A mouse on the left-hand side of your keyboard will be more comfortable because you don't have to reach as far. Even if you're right-handed, it doesn't take that long to get used to the mouse on the left-hand side. Try it!

Document holder. A document holder makes your neck more comfortable because you don't have to twist to see your document. It's better for your eyes too — your eyes can focus more easily when your document and the screen are close to each other.

Clock. It's easy to get sore eyes while working on a computer because we sometimes forget to blink! It's a good idea to turn away from your screen every so often to check the time on the clock or to look out the window.
