Give each child a chart marked with three columns: "Word," "Synonym" and "Antonym." As you read preselected unit words to the students, they first write down those words, then fill in the synonym and antonym for each of them. Encourage students to share answers after reading all the words. Assign a point for each correct answer. The student with the most correct answers receives a prize. Modify the words for different vocabulary levels among students. For students to play in groups, use four words for each round; after each round, a different child marks the words.
Arrange the students in two lines; each line is a team. Write preselected unit words with either synonyms or antonyms on cards. Hold up two of the cards. The first student from each line should go to the board and write either "synonym" or "antonym," depending on the relationship. If students identify the pair of words as antonyms, they must also write a synonym that corresponds to the words. If they identify the words as synonyms, they must also write an antonym. The first team to write a correct answer gets a point. Teams can compete for a specified number of points or until every player takes a turn at the board.
Partners, or small groups of three or four, receive a premade deck of antonym cards (a deck of index cards on which you write antonym pairs, one word on each card). A deck of 50 cards works for small groups; combine two decks for larger groups. Each student is dealt seven cards. Students take turns asking each other for cards they need to create an antonym match. For example, if a student has the word "difficult," he would ask another player for "easy." If the other player cannot produce the requested card, he fishes for a match by selecting a card from the remainder of the deck. The player who obtains the most matches wins.
Instruct students to write a paragraph about themselves, Then instruct them to rewrite the paragraph by substituting antonyms where possible. After the paragraphs are completed, collect and read them to the class. Students can guess which paragraph was written by each student.
