Materials: sentence (and additional words) written on a piece of paper.
Time: 5 to 10 minutes.
Give students a sentence written on a piece of paper, such as “He watched TV every afternoon.” Provide one students with a word that changes the time of the action, such as “now”. Ask the students to rephrase the sentence accordingly and produce “He’s watching TV now.”
Give the next student another word, such as “I” instead of “He” so the pupil says “I’m watching TV.” Continue until one student makes a mistake or until you’ve gone round the whole class.
