T：Now you can ask me.

S：What can you do.Mr.Liu?

T：I can draw something.Look.(畫一些圖形)I candraw some shapes.(板書shapes)

T：Now I’m going to draw another shape.Look!(畫一個三角)

angle

What shape is this?

T：We say this is an angle.(板書angle)

Ss：Angle.

T：(再以其一邊畫一個三角)How many angles canyou see?

T：Then.what shape is this?

T：It’s a triangle.

2.Learn the new word“rectangle”.

T：Look.here’s an English book.Who can draw ashape of this book?

Sl：I can.

T：Come to the blackboard and show us how to doit.

(這句話在解決實際任務時出示．讓學生在真實情景中學習新句子，實現了英語與實際生活的結合。真正做到學以致用。然后教師指導學生正確朗讀，有效避免了學生把這個長句子讀破的情況。)

學生在黑板上畫英語書的外框形狀

rectangle

T：Good.Look，what shape is this?

T：It’s a rectangle.(板書rectangle)

Ss：Rectangle.

(通過學生之手畫出圖形，然后教授新單詞，實現了師生互動，形式新穎，學生饒有興趣。)

T：The English book is a rectangle.The blackboardis a rectangle.too.What else?

3.Learn the new word“square”

T：Good.Now look，(兩手夾住一張軟盤，讓學生看側面)What shape is it?.

T：Now，look，it’s a circle.

Ss：Circle.(學生兩人一組以“開火車”形式操練。)

(通過學生之手畫出圖形，然后新授單詞，實現了師生互動。)

Step 3 Cpnsolidation

1.課件出示以下3張圖片

T：Look，the clock is a triangle.And…

S：The blackboard is a rectangle.

2.Say a rhyme

T：Now if you’re Miss Li.What Would you say to thestudents?Now come on，have a try，I’m sure you can doit.(叫一學生上臺做老師，與其他同學對話互動。)

(本環節是本課一個大膽的嘗試，即在打開課本之前，讓一個學生扮演Miss Li，然后根據教學掛圖與全班同學進行對話互動，因為課文前半部分并不難，這是很好的綜合實踐的機會。)

3.1ealTl Part A
