T: Good idea! We usually eat birthday cake. Look at here. (The teacher points to the screen.) Here is a big birthday cake. Can you guess how much it is?

(Let students guess the price of the birthday cake.)

(Design purpose: the guessing price task will help students review the cardinal numbers they already learned, which will make the learning of the ordinal numbers easier.)

2. Presentation

Step1. Teach the new words.

T: Well done. Now we've known the price of the cake, but do you know who will get the cake?

Ss: ...

T: Whose birthday is today? Put up your hand.

(If there's any students putting up their hands, guide students to sing "Happy Birthday to You". If not, then ask "When is your birthday?")

T: You see, every one's has birthday, and our birthdays are in different months. Then who can tell me how many months there are in a year?

Ss: Twelve.

T: Do you know what the name of each month is?

Ss: No.

T: Ok. I'll show you. Look at the screen; this is January, read after me, "January".
