Introduce the grammar by showing the PowerPoint presentation and handing out the worksheet to practice some conversations.
Let the students practice reading the names and words in the worksheet by repeating after the teacher.
Students choose words from a box at the right corner of the worksheet that correspond to the picture and write them in the blank spaces under each picture.
After the students finish writing, they will work in pairs and play the roles in the sample conversation by changing the underlined words. If a student gives the correct answer, he or she can get one point; otherwise, no points.
