【教案】
Teaching aims
Knowledge aim: students will know the pronunciation of the group of letter “ear”.
Ability aim: students can read words with “ear” when they learn vocabulary.
Emotional aim: students will be more interested in speaking English.
Key and difficult points:
How to pronounce the group of letter “ear”.
Teaching procedure:
Step 1: Warming-up
After greeting students, the teacher plays a game to warm up the class: I say you point. The teacher speaks out a certain part of the body and students point it quickly. For example: point your eye! Point your ear! Point your hand!
Step 2: Presentation
Draw a ear on the blackboard and ask students what it is. Write down the word. Then ask what ears can be used to, and they will say we use ear to hear something. Write down word “hear”. Then do the action of hearing and put hands near the ear, and write down the word “near”.
Ask students to read the three words after the teacher, and find out the similarity among them. After discussion, they will say all these words have “ear”. Then ask students how to pronounce this group of letter. We will know it pronounce as /ir/.
Step 3: practice
Give students some other words with the group of letter “ear” and ask students to read them by groups. For example, a sentence “my dear, your tear is clear in my mind for years”. Then students can have a brainstorming and think of more words with “ear”.
Play a game Hot potato to practice these words. The teacher plays a piece of music. When the music is playing, students pass the ball from one to another. When the music stops, the one who gets the ball should read words on the blackboard.
Step4: Production
Do a chant with students: put your ear, near my ear, and you will hear, and you will hear, and you will hear, NOTHING!
