Let each student take a piece of colored cloth in his hand (other colored things can be brightly colored without cloth) and so on. When you walk to the podium, let different people take turns to raise the cloth in their hands to show their class, such as Class 2 12. First shout slogans, the first sentence xxxx (at this time, let two rows of people who can express "two" in the first round raise their hands), the second sentence xxxx (at this time, let them show their hands) 12), and the third sentence is changed to the fourth sentence of "two" There will be a lot of ideas, which may be a little troublesome to practice ~
