Transcription (Copywork)
A child learns the physical skills of learning to write, first by perfectly forming each letter, and later by copying sentences or paragraphs. In the beginning, copywork is no more than letter practice - the child works on forming letters perfectly, with the emphasis on neat, accurate formation--quality rather than quantity. A Year 1 child should do only as much as he can do neatly in ten minutes, perhaps only a single word, or a few examples of one letter, such as "a." Some children may not have sufficient muscle coordination to begin writing until 7 years old.It is through transcription that specific skills such as punctuation and mechanics (what a paragraph is, when to use capital letters) are picked up. Copywork done properly forces a child to slow down and absorb the punctuation details, notice capitalization, and internalize sparkling, well-written prose. Copywork is usually done daily, but children who are exceptionally resistant to writing may do it two or three times a week.
What should be transcribed? Since modeling excellence in writing is important, children should copy literary examples - poems, scripture verses, passages from wonderfully written books, memorable quotes. For that reason, using a child's own creative writing for copywork is not recommended. Some members like to collect and prepare memorable sayings and advice for use as copywork, but that is not necessary - you can use poems and passages from the child's school books. Some parents choose copywork passages that include spelling words or punctuation examples that they want their child to learn. Many children like helping to select their copywork.
Shakespeare lines, Bible verses, morals from Aesop's Fables, proverbial advice or wisdom (including Proverbs), memorable quotes (some collect these and keep them in a jar for their children to pull out at random for daily copywork), hymns, The Preamble to the Constitution, George Washington's Rules of Civility (

Copywork continues through all twelve years of a child's education, although an older child may do his copywork in a copybook of quotes and quips that he chooses on his own.
