Effective tips for teaching fourth grade vocabulary include explicitly teaching new words to the students and providing repeated exposure to new vocabulary, suggests K12 Reader. Teaching prefixes also makes teaching and learning new vocabulary easier.
One method of teaching fourth grade vocabulary is to teach the words explicitly. Make a list of new words for the students to learn based on existing reading selections. Explain the meaning of each word, give examples of words that mean the same thing as the selected word, and give examples of words that mean the opposite. Use the word in several different sentences so that students learn how the word is used in context. Explain what type of word each term is, such as noun, verb, adjective, or adverb. Provide students with more exposure to the words using articles and stories that contain the words.
Another way to teach fourth grade vocabulary is to teach common prefixes. Explain that a prefix is a group of letters that attach to the beginning of a word that changes the word's meaning. Give an example, such as the prefix "un-" meaning "not" or "the opposite of." Adding the prefix "un-" to the word "happy" makes the word "unhappy," meaning "to not be happy" or "the opposite of happy."
