In my opinion, they completely lacked some extra work. The examples that were counted in the lesson were counted significantly earlier than the other students. I think that the teacher could have written extra examples or some application word problem for the pupils on one of the side boards. About a minute remained until the end of the hour. The teacher asked the students how they worked and how they did. Pupils gave thumbs up / horizontally / down.
