Problem: Article: Doodling is a simple way to practice making writing movements with your shoulder and forearm muscles without having to construct precise letters. You can doodle some shapes and symbols used in the alphabet to get move comfortable with curves and angles. Common alphabet shapes you can practice are /////s, \\\\\s, +++++s, and OOOOOs. You can also practice waves and zig-zags for other letters of the alphabet. It is easiest to begin with the individual letters of the alphabet before moving on to more complicated words and sentences. Begin by writing the alphabet in all uppercase letters and all lowercase letters. Then, you can start writing the individual letters both uppercase and lowercase, together (for example, Aa, Bb, Cc, Dd, Ee, Ff, etc). Practicing writing the alphabet letters in small groups can help you conquer writing out similar letters in smaller portions. By focusing on groups of letters that have similar shape, stroke count, and structure, you can solidify the the movements necessary to write out those letters. All uppercase letters should be the same height. The uppercase letters of the alphabet can be divided into these smaller groups:  Uppercase letters made using one stroke of the pen.L,V,U,W,Z,C,O,S  Uppercase letters made using two strokes of the pen.B,D,J,K,M,N,PQ,R,X,T,Y,Z  Uppercase letters made using three strokes of the pen.A,E,F,H,I While uppercase letters should all be the same height, lowercase letters should vary in height. For example the letters in group 1 should be smaller than the letters in group 4, since the letters in group 1 are all rounded letter whereas the letters in group 4 they have longer tails and stems.  Lowercase letters - group 1.m,n,r,u  Lowercase letters - group 2.a,c,e,s,o  Lowercase letters - group 3.b,d,h,j,g,p,q,f,y  Lowercase letters - group 4.v,w,x,z Everybody has their own style of handwriting, but there are certain sequences when writing out the letters that make it easier to move on to the next letter. For example, rather than starting a lowercase 'e' with the bottom tail and bringing your pen up and around, begin with the short line in the middle of the letter, and bring the pen out, up,  around, and down, so you can move to the next letter naturally. Handwriting notebooks usually consist of writing spaces that are lined in different ways to help with letter sizing and proportion. Repetitive practice writing out letters and sentences can make your handwriting neater and easier to read. Maybe you noticed your handwriting looks a lot better when your letters are more curvy and loopy. Maybe it's easier for you to write comfortably when your letters are bigger than your usual handwriting. Whatever it may be, practice writing with different styles like loopy, bubbly letters, angled, sharp letters, or narrow, tall letters to see what is easiest for you to write and for others to read. There are a million ways to write your letters, experiment to find what works best for you. If you just received a birthday card from your uncle, and you really like the way he writes his J's and c's, get some tracing paper, place it on top of his writing, and trace away. This will help with recognizing and imitating different elements that you want to incorporate into your own writing. As you progress to writing words and sentences, writing slowly will help you identify areas of your writing that need improvement, such as letter spacing, word spacing, letter size, and slant. By taking your time, you can focus on making your letters uniform and sharp. Write out your to-do list or grocery list by hand. Doodle while you're on the phone. Keep a journal and write about your day. The more you practice, the better you will become.
Summary: Doodle. Practice writing all the letters of the alphabet. Focus on writing just the uppercase alphabet letters. Focus on writing just the lowercase alphabet letters. Practice with directional charts and handwriting workbooks. Experiment with different writing styles. Copy handwriting that you like. Write slowly. Practice whenever you can.

In one sentence, describe what the following article is about: Use a long-handled brush to scour the surface of the shingles and loosen stuck-on mold while it's dry and brittle. Focus your attention on the heaviest growth and hard-to-reach areas where the shingles overlap—the chemical treatment will take care of the rest. Make sure you’re wearing your respirator during this phase to avoid breathing the mold particles that will be floating around. To get rid of mold and other types of growth for good, it’s best to use a powerful chemical agent like chlorine bleach. You can whip up your own basic cleaner by combining one quart of bleach, one gallon of water, and ¼ cup (60ml) of trisodium phosphate (TSP). For maximum coverage, use a pump sprayer to disperse the solution.  The chlorine will kill the mold-causing bacteria while the TSP will help remove stains and discoloration. Never combine bleach with any product containing ammonia. This can produce toxic chlorine gas which can be extremely hazardous to breathe.  If you’d rather minimize your handling of chemicals, keep an eye out for preformulated treatments such as Wet & Forget or Moss Out at your local home improvement center. Start on lowest row of shingles and work your way backwards to the upper part of the roof. This will prevent the solution from draining in your direction. Continue spraying until you see runoff, then let the chemicals sit for 15-20 minutes to soak in and begin attacking the mold.  Though it may seem like common sense, using a pressure washer is not advisable. The force they generate is enough to damage delicate shingles.  The best time to clean your roof is during cool or cloudy conditions, when the solution won’t evaporate before it’s had a chance to be effective. Just make sure the forecast doesn't call for rain—a heavy downpour could wash away all your hard work. Empty the sprayer and fill it back up with fresh water, or snake the garden hose around to where you are. Sweep the stream over every part of the roof that you just sprayed to wash away the concentrated chemicals. Any remaining traces will dry naturally in a few hours. If not properly rinsed, chemicals like bleach and lye can cause permanent damage or discoloration.
Summary:
Scrub away the thickest buildup. Mix up your cleaning solution. Spray the entire roof thoroughly. Rinse the shingles.
