Most students, especially young kids of elementary schools, they could not concentrate on class for a very long time, so these songs and chants are necessary. If you add such activities as some songs and chants that students like, you can not only attract students' attention, but also cultivate their interest in learning. Therefore, combining knowledge and activities in the classroom allows students to learn while playing and even achieve better effects.
