Let students pay attention to the word “than”. Ask students to circle this word in their books.

T: When should we use this word? And where should we put it?

T：Who is taller than you? / Who is older than you?

S：XXX is taller than me. / XXX is older than me.

Students make their own dialogues like the model.

2. Show time.

The teacher gives stickers of dinosaurs to students if they do a good job.

3. Play a chain game.

One student stands up and asks, “Who is taller than me?” If someone thinks himself/herself taller, he/she can stand up and answer，“I’m taller than you.” The second student continues to ask the question if he/she is really taller than the first one. Otherwise，he/she should sit down. The student who is taller keeps asking the same question. Find the tallest student in class in this way.

At last，all students try to say, “XXX，you’re the tallest one in our class.”
