Every school year students in grades 7 - 9 at our school practise the irregular verbs in order to automate the use of them both in written and spoken English.

The teacher shows the students a video presenting facts about sleeping and dreaming. The students watch it once. Then the teacher divides them in pairs or in groups and presents the task to the groups: “You will watch the same video again, pay attention to the facts and try to remember as many as you can, at least 5. Then, each group will write what you have remembered. You can’t write while the video is running.” The students have 5 minutes to fulfill the task, after that the groups share what they have written. The group who has written more facts than the other groups is the winner.
