Opposites can be an overlooked lesson for English as a Second Language. They provide a good way of categorizing certain vocabulary - such as positional directions and descriptive adjectives. Even if a student cannot recall both of the words in an opposite pair, they benefit from the ability to negate the word they can recall and still communicate effectively.
In my class, we use this worksheet to really take a look at opposites. The 4-page worksheet of 96 pairs of opposites are first translated into their native language - filling each translation on the line below the word. Then we search for words that are used in more than one English pair of opposites. We look for English synonyms, words that are similar to the native word, and false friends.
At a later class session, we put our opposite memory to the test by playing a friendly round of Opposites Bingo.
