Q: Aim to teach the subjects you know best. You are more likely to get hired to help someone with their essays and reading comprehension if you are an English Major, for instance. If you are hired to teach something you are not an expert in, get to know it. If you are teaching something you have a strong personal knowledge of but have never learned in school, such as your own first language, take some time to study academic literature, lesson plans, and the rules your student must learn. If you are teaching your favorite thing, understand that your student may be struggling to understand it and may therefore not share your enthusiasm. Plan out each session ahead of time. Each lesson should include review of the previous lesson, introduction of a learning objective, and activities to help students practice applying what they have learned. Start with easier material, and make sure the student understands it before you move on. Let them do the parts they seem to understand without interfering. Move in to support them when they struggle with more difficult tasks. Guide students towards answers, but do not give them before the student has worked them out on their own. If a lesson doesn't go as planned, re-plan. Repeat tasks and take new angles on material that is harder for your student to learn. Don't try to cover everything that comes up during class. Do not try to correct every mistake that your student makes. You can quickly overwhelm a student with information. Instead, take note of mistakes, but focus on your lesson goals. If you are teaching English or a second language, never correct your student's grammar while they speak. Instead, model correct language usage. Ask your student to demonstrate what they have learned with you. Give quizzes, ask for verbal summaries, and check their work. You can also ask to be shown current test scores and completed class work to see if your student is demonstrating their knowledge outside of tutoring sessions. If a student does not seem to be absorbing the material, go back and re-explain from a different angle. Try starting further back, so your student can build up to the new material. If your student is getting teary, frustrated, or seems blocked, switch activities or give them a break.
A: Know your subject area. Make lesson plans. Teach what you came to teach. Asses student comprehension.

Q: Find the concentration of the acid solution on the label, or in the word problem you are working on. This number is often written in units of molarity, or molar concentration, abbreviated as M. For example, a "6M" acid contains six moles of acid molecules per liter. We'll call this starting concentration C1. The formula below will also use the term V1. This is the volume of the acid we will be adding to water. We probably won't use the entire bottle of acid, though, so we don't know what this number is yet. The desired concentration and volume of acid is typically determined by a school assignment or by the requirements of the laboratory you are working in. For example, we might want to dilute our acid to a concentration of 2M, and need 0.5 liters (0.1USgal). We'll call this desired concentration C2 and the desired volume V2. If you are using unusual units, convert them all to units of molar concentration (moles per liter) and liters before you continue. If you are not certain what concentration or volume of acid is required, consult your teacher, a chemist, or an expert in the task you plan to use acid in. Whenever you prepare to dilute a solution, you can use the formula C1V1 = C2V2. words, this means "the initial solution's concentration x its volume = the diluted solutions' concentration x its volume." We know this is true because concentration x volume = the total amount of acid, and the total amount of acid will remain the same as it is added to the water. In our example, we can write this formula (6M)(V1)=(2M)(0.5L). This term, V1, will tell us how much of the initial acid solution we need to add to water in order to end up with the desired concentration and volume. Rearrange the formula as V1=(C2V2)/(C1), then plug in the numbers you know. In our example, we would end up with V1=((2M)(0.5L))/(6M)=16 liter (0.0USgal). This approximately equals 0.167 liters (0.0USgal), or 167 milliliters. Now that you now V1, the amount of acid you'll be using, and V2, the amount of solution you'll end up with, you can easily calculate how much water you need to make up the difference. V2- V1 = the volume of water required. In our case, we want to end up 0.5 liters (0.1USgal) and will be using 0.167 liters (0.0USgal) of acid. The amount of water we need = 0.5L - 0.167L = 0.333L, or 333 milliliters.
A: Check what you already have. Decide on an end result. Write the formula for calculating dilution. Solve the formula for V1. Calculate how much water you'll need.

Q: Microsuede is used as a fabric for many items, including clothing, towels, drapes, and mops. These can all be cleaned easily, but handwashing is recommended. Using a spray bottle filled with alcohol or polyester cleaner, spray soiled areas and blot or dab the stains with a clean cloth. Before cleaning any fabric, always read all tag directions regarding proper washing instructions. Perform a small test patch on the fabric somewhere unnoticeable before applying any cleaning solution to the entire cloth. You only need the sink about half full or three-quarters of the way full, depending on how many items you'll be washing. As the water is running, mix in one-half to one ounce (one to two tablespoons) of liquid laundry detergent or mild soap. Wash your microsuede items one at a time. Tackle stubborn dirt with a soft-bristled brush. Alternatively, you can wash microsuede items in the washing machine on the delicate or hand-wash cycle. Wash microsuede items alone together, as this material tends to collect lint from other fabrics. Do not use bleach products or fabric softeners on microsuede. When your items are clean, squeeze each one to get out the water. Lay a clean, dry towel flat on a counter or table. Lay a microsuede item flat on top of the towel. Roll the towel up tightly with the item inside, and the towel will absorb the excess moisture. Unroll the towel and hang the item to air dry. Repeat with all your items, replacing the towel with a dry one if necessary. A dryer can be used on low-heat or a no-heat setting, but it's best to hang microsuede fabric on a clothesline or on hangers to air dry.
A:
Spot clean stains. Fill a sink with warm water. Dry the items.
