第一课时
Section A
Step 1 A game
Prepare a box with some things in. Ask the students to guess what is in it. Then ask one student to feel the things in it and tell the others what they are.
Review the word spelling of these things.
Step 2 Watching and writing
1a. The students look at the picture and talk about the things they see. Then write the things in the correct columns in the chart.
Step 3 Talking
Take out the things that are in the box. Ask, “Do you know whose book is it? Do you know whose hat is it?…..” The answers will vary. When the students say, “Maybe it is…”, help them to say it in another way, “It may be…. It might / could be….” When the students say, “It is…..”, tell them to say,” It must be……” Point out when we are not sure about sth, we can use “may, might, could” to make inferences. When we think something is probably true, we can use “must ”.
Step 4 Listening and practicing
1b. Students listen and match each person with a thing and a reason.
Ask the students to practice the conversation in the picture in 1a. and then make similar conversation to the one in 1c.
Step 5 Listening
Say “Bob and Anna found a backpack in front of their school. They are guessing whose bag it is. Listen and write down the things in the backpack.”
