Make a pack of flashcards containing a range of adjectives. Each word must have an "opposite" on another card. For example, if you write "large" on one card, write "small" on another card. Get the children to take one card and then walk around the room and talk to other children to find the opposite word. The students must ask two questions to find the correct opposite. For instance, the student with the word "large" could ask other children if their word starts with "s" and how many letters the word contains.
Have two sets of cards, one for nouns and one for adjectives. The students take one card from each pile and draw a picture describing what they have selected. For example, a student picking "dinosaur" and "magical" must illustrate that in his picture. Have the students swap pictures and try to guess each other's adjectives.
Prepare a simple story for the students but leave out all the adjectives and replace them with a blank line. Ask the students to fill in the missing words. The objective is to make the story as silly and funny as possible. Encourage the students to use their imagination and choose adjectives that might not fit but make the story comical. Instead of writing the "nice" teacher, the students could choose "hairy." Get the student to write in pairs and then read their stories. The class votes on the "winning" story or the teacher can choose the winner, based on the volume of the laughter. Alternatively, have students spot the adjectives from a book that the teacher reads out loud.
Prepare a pack of flashcards, each containing an adjective. The children take turns choosing a card and act out the adjective. For instance, if a child picks up a card with "rainy" on it, she could pretend to put up an umbrella or even make rain gestures. The child who calls out the right word then gets a turn.
