三、 Teaching steps

Step One Warming up

* Play an English song before class.

* Revise some school things by asking questions.

e.g.: What's this? Is this a ...? How do you spell it? etc.

* Learn the new words in, on, under, behind ... by helping the teacher find the lost things.

e.g.: T: Where's my English book?

　　S1: It's here. / I think it's ...

　　T: Oh, it's on the desk.

　　...

　　T: Where're my color pencils?

　　S2: ...

Teach the new word "where" and the use of "they".

* Consolidate the prepositions by looking at the screen and answer the questions:

Where's ... ? Where're...?

Step Two Game: Hide and look for things

Students hide and look for the school things in pairs. One student hide one school thing and ask: Where's...? Where're...? The other student guess and answer: It's in your desk. They are in your pencil case. etc. Ask some pairs to share their performance.

Step Three New words learning

* Show the students a picture of a room, tell them this is a bedroom, let the students list the things in it first. Then show them the whole picture, teach the new words, ask where the things are, let the students answer, using the prepositions.

* Repeat with a sitting room and a study, teach the new words and practice in the same way.
