 Here's another teaching idea for the present continuous tense. Here now we'll ask our students to compare two different photos with a number of activities going on in each one. The students will be paired up in student A and student B. The teacher will give the pairs a time limit in which to make statements about each one's picture, hopefully in the process identifying differences. What we'll have the students do is make statements such as, the man is looking at the statue. Student B will then find a man near the statue and say, oh, in my picture the man is taking a picture of the statue. They'll pan the room, find the various differences, and make a note of them. At the end of the time limit, the teacher will gather the students up and ask them to report their findings and their differences. In this activity, remember it's absolutely crucial that the students don't show each other their pictures, but rather describe them verbally.
