Teacher B adapted Activity 2 by doing two format switches. The first switch was from reading and drawing lines to speaking and matching cards. Instead of having the learner connect the two sentence halves by drawing a line in the book, he transferred the sentence halves into cards. The second switch was from pair to group work. Instead of having them work in groups of six. The teacher assumed that telling the students what to do was enough preparation for the activity. It didn’t work. Once he had demonstrated what to do, they understand.
