One interesting activity can be done most effectively in the days prior to parent-teacher conferences. Tell the students that you will be meeting with their parents soon, and ask them to make up two lists of adjectives. The first list will be words that they would like for you to use during the conference, and the second list would be adjectives that they would not like you to use. Prizes can be awarded for the most creative lists and the most descriptive lists.
Another way to encourage the creative use of adjectives is to have the students, in groups of two to four, choose a noun. The students then individually come up with two or three adjectives starting with the same letter as the noun. The students may use dictionaries to encourage creativity and the expansion of their vocabulary. Once they have found two or three appropriate adjectives for the noun, the students return to their groups and choose the best adjective for the noun. Award prizes or points to the group with the best noun and adjective pairing.
Arrange the students into groups of three and have them choose another noun. Have one student in the group make a sentence using the noun and an adjective. The second person in the group must make a new sentence using the noun and the comparative form of the same adjective. Then the remaining student must make a third sentence using the noun and the superlative form of the adjective. Do at least three rounds of this game so everyone has a chance to do a superlative adjective.
Have the students arrange themselves into small groups. Each student within the group composes a sentence with several nouns but no adjectives. The students then pass their sentences around the group, with each student adding an adjective to each sentence. When all students have added an adjective to each sentence, the group chooses their silliest and most creative sentences. The class as a whole votes on which group had the best sentences.
