Repetition is a common strategies used by teachers to aid students in remembering what has been taught. In language arts, repetition is the guiding light for teaching vocabulary and grammar, especially difficult subject matter such as the multiple meanings of words. The one drawback is that repetition can bore students and teachers alike.
For this strategy, begin by explaining that words sometimes have more than one meaning. Give an example. Ask the students if they can think of some. Define the words for the students or ask them to define them. Write sentences for each meaning.
Now, have the students read the sentences with you, but have a bit of fun by reading each sentence in a different tone of voice (soft, squeaky, grumpy, etc.) For instance, if the word is pet, use one intonation for, "She likes to pet the dog on the head," and different intonation for, "The yellow cat is my pet." Have the students repeat the sentences using the same intonation after you. This is silly, but the processing done by the brain when the various words are spoken in different voices adds stimulus that helps trigger memory. An alternative method for this is to sing the sentences.
Books that repeat a word in rhyme also helps reinforce meaning. In teaching words with multiple meanings, have students read books such as The Dove Dove by Marvin Turbin or Live Lions Live on Land by Carey Molter. Repeated reading of these books will assist students in meaning making of the vocabulary.
