Q: If possible, it can be helpful to dedicate a whole room to homeschooling, as it keeps the mess out of sight and helps keep your kids on task. You can use a family room, den, basement, office, or even an extra bedroom. You may even be able to convert a shed with electricity into a homeschooling room. It's entirely possible you don't have the space to devote a whole room to homeschooling. If that's the case, try picking a central area, such as the living room or dining area. Choose an area where you can add some storage, so that you can hide school stuff away when your kids aren't working on it.  Your dining area is a good choice since you already have a table in place for your kids to use. Even if your kids tend to spread out around the house to work, you should still have a designated area for keeping your school supplies. Pick an area that doesn't have distractions like a television, video game console, or the like. You want your kids to stay on task as much as possible, and distractions won't help with that!  Try to pick a quiet area in the house that doesn't have a lot of extraneous noise. For instance, you may not want to put the room too close to the laundry room. Similarly, while you wouldn't want to cover up the windows, you may want to face the classroom away from the windows. Let any other household members know school is in session by hanging a sign on the door. That way, they won't barge in! Homeschooling can get messy, especially if you're crafting or cutting up paper at all. By choosing a room without carpet, you can sweep up most debris, and if something like paint spills, it's much easier to clean up.  If the room you want to use has carpet, consider pulling it up. You may find hardwood or tile underneath. If it's concrete, you can even just paint the concrete. If you find subfloor, you can put in laminate or another cheap and durable flooring solution. Alternatively, try adding plastic office floor mats. These have spikes that go into carpet to hold them in place and provide a hard plastic surface on top. one or more walls with bright, happy colors if you can. You and your kids are going to spend a lot of time in your homeschooling room, so you might as well make it cheerful. If you're allowed to paint the walls in your home, try choosing a bright accent color for one or two walls, then paint the other walls a more neutral color. You could pick a creamy yellow for sunshine effect or a bright purple if it's your kids' favorite color. Stick up wall decals of animals, flowers, the alphabet, or any fun theme your kids will like. Wall decals make it easy to change out the theme, as you can just peel them off and stick up a new set when you're tired of the old ones.  You can find wall decals at craft stores or online. If you want something a little more permanent, try stenciling the alphabet and numbers on the walls, or having your kids paint a mural together.
A: Set aside a whole room if you have space. Add your classroom to an existing room if you don't have extra space. Choose an area without distractions. Pick a room without carpet or install floor mats. Paint Add fun decals to the walls if you don't want to paint.

Article: If you want your bruise to look real, you've got to pick a good spot for it. Some places don't actually bruise that much, so you've got to pick a good fleshy place on your body, or a place where you might be injured. The best places for fake bruises are usually:  Your forearm. Anywhere on your leg. Your forehead. Your chest or shoulder. Don't put a fake bruise near or around your eyes. Real looking bruise in place? Check. Unsuspecting friend in sight? Check. Wait for a good moment, when you're both doing something physical or playing in some way, then fake an injury. Wait until your friend comes close and then grab the area with the fake bruise suddenly and start hollering.  Really play it up. Pretend that you're in pain and look angry. It's a good way to build some sympathy or freak out the victim of your prank. If you don't want to go through all the acting trouble, you could always just whip out your bruise and say something like:  "You should see the other person." "I got this working on an oil rig." "I fell off my dad's motorcycle."
Question: What is a summary of what this article is about?

Article: Some trucks may only be able to dump the rocks in one big pile, but some trucks can let the rocks out a little at a time, spreading them across the span of your driveway, which will save you a lot of work. Use a wheelbarrow to distribute the rocks evenly along the length of your driveway.  Then use your shovel and hard metal rake to spread the rocks evenly across the width of your driveway. You can also try driving over the area repeatedly with a heavy vehicle such as a large truck. If you only have one layer, you can move to the next step. Your driveway should be slightly elevated in the middle and lower on the sides to promote water drainage.  You can achieve this by raking in from the sides towards the center so that the rocks are slightly piled higher in the center.  You could also add some additional gravel down the center of your driveway and slowly scrape it towards the sides a little at a time. Don’t go too crazy with the grading; you don’t want your driveway to look like a pyramid. The ideal grade is very subtle, with the middle 2% to 5% higher than the sides. Be sure to “finish” your project by cleaning up.  Remove the landscape stakes and twine markers.  Put away or return tools that were rented or borrowed, and be sure to pay or thank anyone who helped you with the project. When necessary, rake gravel that gets displaced back into your driveway.  Also think about adding gravel every two to three years to any low or bare spots that emerge over time.
