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?

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.
