Supporting ESL students, forming negatives and opposites
The students can recognise particular words and prefixes that signal negation and use negative forms in creating their own oral or written texts.
Activities to support the strategy
Activity 1: using prefixes to form opposites to create negation
Introduce the use of prefixes to create opposites of adjectives.
Give students a list of adjectives and discuss how to make opposites. Some use totally different words (e.g. large/small) while others can use a prefix to create the opposite (e.g. the opposite of happy can be either sad or unhappy) make sets of cards.
Teacher may say that the use of some prefixes can change the verb to the opposite meaning.
Use a range of prefixes to build understanding that there are various forms that perform the same function and they may change according to the first letter of the base word.
“un” is the most common prefix indicating negation but other common variants are:
Teacher explains that all these prefixes perform the same function - to create the negative attribute or action.
Teacher tip: display this table to help students become familiar with the use of different prefixes.
Activity 2: practising usage
Students can use quizzes on websites, play communicative sorting games to match prefixes to base words and complete sentences using the negative forms to practise usage. (Worksheets such as the one below should be with a partner orally.)
Activity 3: practising using base words in groups
Students research different negative prefixes and make posters of lists for display in the classroom. (See below)
