Steps of a Dictation Lesson
Dictation lessons done the following way usually result in good spelling. A child of eight or nine studies a paragraph; older students study one page, or two or

three pages. The students prepares for the lesson by himself. He looks at any word he isn’t sure of and tries to see it with his eyes closed. Before the dictation begins, the teacher asks him which words he thinks might give him trouble. He usually knows, and she can write them on the blackboard. She asks him to look until he has a picture of the word in his mind. Then she erases each word one by one. If he still isn’t sure about a particular word, she should have him attempt to write it on the blackboard from memory. She must watch closely so that, as soon as he begins to add the wrong letter, she can erase it before it lodges in his memory. When the word is on the board correctly, the student again tries to make a mental picture. Then the teacher dictates the passage, a phrase at a time, and only repeating once. She reads expressively enough to make punctuation evident, and students are expected to include correct punctuation. But she should not say, ‘comma,’ or ‘semi-colon.’ After students have spent maybe ten minutes preparing for the dictation as outlined, there are rarely any spelling mistakes. If there are any, the teacher would be wise to cover them with adhesive paper or white-out to erase the wrong spellings from the student’s mind as much as possible. At the end of the lesson, the child should study that word from his book until he’s sure he knows it. Then he should write the correctly spelled word on the adhesive paper, or over the white-out.
Children cooperate enthusiastically with this kind of lesson because they feel like they have a part in it. It also prepares them for the second thing necessary to be a good speller, which is lots of reading with a trained habit of making a mental image of words as they are read.
Bad spelling is usually a sign of not much reading,

Dictation
Dictation, which reinforces spelling, is when the child writes something as the parent dictates. This is not for testing purposes – the child should be familiar with the passage or sentence being written. You can let them “study” for it first so that he knows how to spell the words. He might close his eyes and try to picture the passage accurately. He might practice words he’s unsure about spelling. Only when he feels he is ready does the dictation exercise begin. This makes it more likely that the child will spell words correctly the first time. Some children are natural spellers and seem to effortlessly absorb spelling from their copywork and reading. For other children, dictation can help polish spelling skills because the child will have to memorize how to spell the word before the dictation exercise begins. The parent then reads the passage slowly and clearly while the child writes it from memory. Some parents use dictation as a way to test their child’s spelling, using misspelled words as a spelling list. But caution should be used because once a child sees or writes a word incorrectly, that incorrect spelling is recorded in his memory. (Sand, rice, cornmeal, salt or shaving cream, which allows misspelled words to be wiped out immediately, is a fun way to practice writing for young children.)
A child does not start dictation until he has mastered handwriting from copywork experience. His first dictation exercise may be a single sentence. By 10 or 11 years of age, he might be able to do a few sentences. Older children might do a paragraph or two once a week.
By 10 to 12 years of age, some children, especially those who don’t learn visually or are dyslexic, will still be having trouble spelling and need extra help. Programs that AmblesideOnline members have used with success are Mary Pecci’s Super Speller and DesignAStudy’s Natural Speller. Sequential Spelling or the book “Seeing Stars” by Nanci Bell may be helpful for dyslexics. Spelling Workout, although popular and effective with some list members, does not follow CM’s philosophy. Spelling Power is also used with success by some list members, but none of the Advisory members have seen it to assess its compatibilty with Charlotte Mason’s methods.

Dictation Level: Grades 4–12
Focus: Spelling
Description: After the student feels comfortable studying and writing words from memory, he graduates to preparing the entire passage and writing it all at once as the teacher dictates it to him. He doesn’t have to memorize the passage, but he does need to study it ahead of time and make sure he knows how to spell every word in it. You can also encourage him to take note of the punctuation and capitalization before you dictate the passage phrase by phrase. For a detailed look at how to do a dictation lesson, watch this video on prepared dictation.
Other Benefits: Cultivates the habit of looking at how words are spelled as you read; reinforces correct punctuation and capitalization; sharpens listening comprehension; increases vocabulary through context; reinforces correct sentence structure; reinforces the habits of observation and attention
