教学重点：能分组用形状设计图形，并对该图形内容进行描述。
教学难点：能熟练使用新句型并结合以前学过的句型对图形内容进行描述。
教学准备：电脑、彩笔、形状卡片和设计用纸等
教学过程：
Step 1 Warming:
Greeting :
T: Hello, boys and girls. Nice to meet you.
Ss: Hello, Miss Huang. Nice to meet you too.
Step 2 Presentation:
T: Now please follow me. Let’s look for some shapes. (板书课题 shape) Look the screen carefully please, what can you see? (课件中出示两辆在起跑线上的赛车，1号车是正方形轮胎的车，2号车是圆形轮胎的车) Ss: There are two cars…
T: Yes, the two cars will have a race. Can you guess which car can run faster? No.1 or No.2 car. S1: No.1 car. S2: No.2 car….T: The competition start, let’s say “come on” together and see which car is the winner. Ss: Come on, come on… (课件中出示到达终点时2号车领先)
T: Which car is the winner? Ss: No.2. T: Why? Because wheels can run faster. (老师边用鼠标指着两辆车上的有关形状的轮胎和旗帜边介绍形状) It’s a circle. Look here, it’s a square. Boys and girls what can you see on the No.1 car? It’s a flag. Is it a circle? Is it a square? It’s a triangle. What shape is the flag on the No.2 car? It’s a rectangle.(板书 a circle, a square, a triangle, a rectangle)
Step 3 Practice:
1. Let students listen and show.
There are five groups and each group has a pair of the four shapes. T says the four shapes and students say after T together and show the shape. Which group is the fastest and which group is the winner.
2. Look for shapes in the classroom and show them.
S1: Look at the window, it’s a rectangle. S2: Look here, it’s a square.
Competition: We say, you do action.
T sticks the four shapes’ cards on the floor of the classroom. When students look for shapes in the classroom, they will look for these four shapes’ cards. T asks one student to show shapes’ cards one by one and all students say the words together one by one, then T asks a boy and a girl to make a competition to listen and jump on the shapes.
Step 4 Presentation of the new pattern:
Game1: Let students do some puzzles. (课件中出示四种形状的碎片)
the No.1 puzzle T: What shape is it? Ss: It’s a square. （板书句型 What shape is it? It’s…）
the other three puzzles Ss: What shape is it? S1: It’s a… S2: It’s a …
Step 5 Practice:
IQ test: Let students do some IQ test about shapes.
(课件中出示一些看形状找规律和移动棍子变形状的拓展思维的题)
Task: Let students guess pictures.
(课件中出示一些由形状组拼的图形，让学生猜形状和图形)
T: What shape is this? S1: It’s a … S2: … T: Guess, what’s this? S1: … S2: …
Step 6 Extension:
Make a picture with the shapes:
Let students choose one shape to make a picture. Then T asks students to show the picture. For example: S1: Draw a shape and ask others: what shape is it? It’s a … Guess what is this, please. Then continue to draw and to ask..

课堂实录评析：
本课的教学内容是单词：circle, triangle, rectangle, square和句型What shape is it? It is a…的学习。设计采取游戏方式开展教学，尝试将美术学科的有关知识有机的融入到英语教学中，配合生动有趣的课件和一些灵活的有关形状的思维题，把小学的美术知识与英语的一些句型、词汇紧密地结合在一起，有效地体现了学科综合化的新课程理念。
这是一节很好的小学英语活动课。首先，这节课层次分明，条理清楚。以游戏的方式引出单词后，通过设计各种游戏、活动、思维题巩固单词，然后通过反散性思维的puzzle引出句型，并通过拓展性的思维题和画画猜图的方式应用句型。其次，在这节课中体现了趣味性原则，在小学阶段应注意以情激趣，以趣助学。兴趣是小学生学习的动力。例如：单词和句型的引出和巩固。英语学习的归属还是实效，在这节课中如在教室找形状和用形状组图形并进行描述都体现了实效性。再是，在这节课中体现了主体性原则，注重课堂及时反馈，强调以学生为中心的小组活动和协作学习，激发不同层次学生的学习兴趣，最大限度地调动学生的主动性和积极性，开发学生在英语和美术学习方面的思维潜力。
最后，在这节课中体现了形象思维的培养，比较注重语言和思维共同发展，尤其是反散性思维的培养。最后的拓展部分让学生用图形画画并猜图形和有关形状的思维题中都体现了这一点。
