According to my observations, there are some differences between grades 1 and 4. Teachers' classroom teaching methods must adapt to students' personalities. Grade 1 will have a colorful slide, carton, and picture. The authentic material is for more than 4th-grade students. One thing that attracts students' interest in both grades is the student center. The teacher will allow students to participate in the classroom as much as possible by playing games, answering questions, and asking questions. This excited the students' interest and allowed them to concentrate on the lesson.
