Pay attention to “twenty, thirty, forty, fifty, sixty, seventy, eighty, ninety”.

The numbers above all end with “-ty”.

Step II Lead-in

T: Look at the box. Can you guess what’s in it? (Point to a box.)

Ss: ... (They may guess different kinds of things.)

T: Look! It’s a pink pig I bought yesterday. It’s fat and lovely. Do you think so?

Ss: Yes!

T: But what’s it used for? (If Ss can’t understand, explain it to the class.)

Ss: ... (Maybe different answers.)

T: Now I’ll tell you. It’s used for putting CDs. Very interesting, isn’t?

Ss: Yes!

T: How much is it, do you know?

Ss: ... ( Different prices.)

T: It’s twelve yuan. It’s on sale, so it’s not expensive.

Write the key words and sentence “expensive / dear, on sale, how much is / for …, It’s …yuan” on the Bb. Explain and have Ss repeat them.

Then practise with Ss, just like this:

T: I’ll ask one of you to be a clerk and I am a customer.

S: May I help you?

T: Yes, I want to buy rulers. Are these rulers on sale?

S: Yes.

T: How much for one ruler?

S: It’s one yuan.

T: Oh. That’s not expensive. Okay, I’ll take two. Thanks! (Write “I’ll take ...” on the Bb.)

S: You’re welcome.

Step III Presentation

Role-play.

Deal with Part 1 on Page 56. In this step, Ss do some oral practice in pairs using the target language. They should stand in front of the class to present their dialogues.

Put some pens, erasers, books, pencil-boxes, rulers on the teacher’s desk.

A sample conversation:

S1: May I help you?

S2: Yes, I’d like a pen, please. How much is this?

S1: Twenty yuan.

S2: Oh, that’s too expensive. Are those pens on sale?

S1: Yes!

S2: How much for one pen?

S1: Eight yuan.

S2: OK, I’ll take two, please. A red one and a black one. Thanks!

S1: You’re welcome. Goodbye!

S2: Bye!

Ask more pairs to act out their conversations in front of the class.
