The unit rate is a special type of ratio in which the two separate measurements are compared and expressed as a quantity of one.  A "ratio" is any comparison of two numerical measurements. Each measurement is called a "term." A "rate" is a ratio in which the two terms are measured in different units. All rates are ratios, but not all rations are rates. A "unit rate" is a rate in which the second term equals "1." When calculating a unit rate, you need to determine how much of the first term exists for every one unit of the second term. The problem must have two terms, and you must be asked to determine how much of one term exists per unit of the other term.  Common examples include: speed (miles/kilometers per hour), unit price (cost per item), and wage (earnings per hour/week).  If you aren't sure about whether or not you're being asked for the unit rate, look for the word "per" somewhere in the description. Some unit rate problems won't include "per," but many do.  Example: A certain bakery can bake 40 loaves of bread in an 8 hour work day. How many loaves of bread can that same bakery make in one hour? In other words, how many loaves of bread are typically baked per hour? The first term in the problem—the amount you are trying to calculate per unit—will become the numerator (top number). The second term—the unit—will become the denominator (bottom number).  Example: You must calculate loaves of bread per unit of time (in this case, the unit of time is an hour). The total loaves of bread will become the numerator, and the total hours will become the denominator, giving you: 40 loaves / 8 hours To find the unit rate, simply solve the newly written division problem. Doing so will reduce the denominator to "1."  Example: Divide the total number of loaves by the total number of hours: 40 loaves / 8 hours = 5 loaves/hours You should now have your final answer ready.  Make sure that you include both units in your answer. You can either separate the units with the fraction sign (/) or with the word "per."  Example: This bakery can bake 5 loaves/hour. Alternatively, you could write, "This bakery can bake 5 loaves per hour.”

Summary: Understand unit rate. Look at the data. Rewrite the data as a division problem. Divide both values by the denominator. Write the solution.


Research online tutoring companies and websites that match tutors with students looking for assistance with specific subjects.  Some of these companies help clients locate a tutor in your area, but others pair tutors with a client online and you work remotely. Applications to become a tutor are typically completed online. Depending on the website and service, you may be required to take screening exams or undergo background checks. If you are hunting for a tutoring job and would prefer to meet with your students in person instead of online, visit local learning centers and community centers.  Most communities feature a branch of a national tutoring company such as Sylvan or Kumon. If you live in a larger town with a university, there may also be tutoring positions through testing review companies such as Kaplan or the Princeton Review. Contact these places and ask if they are hiring tutors. It’s also a good idea to visit local community centers that may offer after-school tutoring programs and be looking for qualified tutors. At the very least, these places may be willing to advertise your tutoring services. Many summer camp programs and after-school programs offer tutoring services to students who participate in their activities. Contact the administrator of the program, discuss your qualifications, and ask if they need any tutors. Even if they do not currently have available positions, the administrator may know of another program that is hiring or may be able to recommend that you speak with someone else. Many community colleges and universities hire qualified tutors in specific subjects, so check with human resources at a college or university in your area to find out if there may be available tutoring positions.  While these positions are usually advertised online through the college or university’s human resources website, you can also call or email. Find out if there are continuing education programs in your area that may also be interested in hiring qualified tutors. Public libraries, for example, sometimes host these programs. If you are interested in seeing more of the world while you are tutoring, you might consider looking for tutoring positions abroad. There are specific tutoring companies that specialize in matching tutors with families or agencies abroad, so conduct your own research and explore these potential options. Keep in mind, that these are usually more full-time and long-term positions. If you are looking for a part-time commitment, this might not be the best choice. If you are having a difficult time locating a tutoring position with a specific company or center, or would just like the freedom of working on your own, you may want to establish your own tutoring business. If you decide to tutor privately or start your own business, think carefully about where you will meet clients. While your home or a client’s home may be convenient, you may prefer a place that is public such as a library or coffee shop. This way you do not have to provide your address to strangers and it is a safe location where you could get help if needed.

Summary: Research online tutoring companies. Visit local learning centers and community centers. Talk with administrators of summer camps and after-school programs. Check with community colleges or universities in your area. Consider tutoring abroad. Establish your own tutoring business.


These will be used to set the walls of your foundation.  Each of these boards will need to be about 2 feet by 10 feet (an inch or two thick).  The shorter sides of the boards will sit down, on top of the initial concrete layer.  You will need enough boards for both the inside and outside of your trench footing, so that there is no space in between the boards.  You can add in a little dirt on the outer part of the outside boards to help them stand firm and upright.  Use metal bars outside of the wooden frames in order to hold the boards tightly together.  You can also cut boards or plywood strips 6 to 8 inches wide and 2 to 3 feet long and use duplex nails to span across the joints of your foundation boards to hold them together. Be sure all of your staking is sturdy or you risk “blowing out” the boards and losing all of the concrete. Use plenty of stakes to prevent this from happening. Once more, make sure that you have the correct mixture of concrete. How to Make Concrete In general, you should form the entire job and pour all the concrete at once with a concrete truck.  How much wall is exposed over top of the ground depends on the level at which your building will rest. Drill 3-4 holes about 6 inches apart.  Do this to each side.  Insert a pin into each of these holes.  This is important because if you do not insert the pins, your walls can shift, causing the building to collapse. Pour the second and third walls coming off of the initial wall.  The concrete will form over the pin and join the walls together. Reinsert pins into the sides of the second and third walls. You can use a hand float and go over the tops, making sure there are no cracks and crevices.  You should also use an edger to go around the edges and smooth them over. Let your concrete dry, and then remove the frames.  You will want to do this soon after the concrete dries, otherwise the wooden frames can get stuck.  Try to pull them up from the top, so as to not damage the newly poured foundation walls. These sprays can be found at most hardware stores at very low prices.  It is basically a can of spray cement.  Adding this extra layer of protection will prevent water and other liquids from damaging your foundation.  Make sure to spray on both sides of the wall.
Summary: Set up your wooden frames. Mix concrete and pour your foundation walls. If you are pouring next to an old foundations this should be pinned to the new foundation wall. Smooth over the tops of the concrete walls. Remove the wooden frames. Spray your foundation walls with a waterproof coat.
