1. Concise and clear: For students in the lower grades of primary school, the content of PPT should be concise and clear, avoiding too many words and complicated charts. The content on each slide should be concise and to the point, highlighting the key points, which is convenient for students to understand and remember. Illustrated with pictures and texts: PPT design should pay attention to illustrated with pictures, charts and animations to present knowledge.

2. Highlight the key points: PPT design should highlight the key points and present important knowledge points or problems in an eye-catching way, so that students can quickly grasp the key points. At the same time, we should also pay attention to the hierarchy and logic of knowledge points to help students establish a clear knowledge structure.

3. Strong interactivity: PPT design should pay attention to interactivity, guide students to actively participate in classroom activities through questions, discussions, games and other forms, and stimulate students' interest and initiative in learning.

4. Scientific use: PPT is only a tool to assist teaching and cannot completely replace the teacher's explanation and blackboard writing. Therefore, when using PPT, we should choose and design according to the teaching content and the actual situation of students, so as to avoid relying too much on PPT and ignoring the advantages of traditional teaching methods.

5, pay attention to beauty: PPT design should pay attention to beauty, color matching, typesetting design, font size and so on should meet the aesthetic habits and needs of primary school students. At the same time, too much decoration and irrelevant content should be avoided to avoid distracting students.

The way to have a good class.

1. Get ready before class: Before class, students should carefully prepare textbooks, notebooks and stationery, so as not to affect the learning effect because of the lack of necessary stationery during class. At the same time, teachers should also prepare lesson plans and courseware in advance to ensure clear thinking and rich content in class.

2. Listen carefully: listen carefully in class, think positively, keep up with the teacher's ideas, pay attention to the teacher's explanation methods and ideas, understand the knowledge points, and don't interrupt the teacher's explanation easily. Note-taking: Take notes carefully in class, and record the key points and difficulties that the teacher said, so as to review and consolidate after class.

3. Active interaction: In class, we should actively interact with teachers and classmates, participate in class discussions and questions, share our own ideas and opinions, and solve problems together. This can improve your learning ability and thinking ability. Review after class: review the knowledge points learned in class in time after class to deepen the understanding and memory of knowledge.

4. Listen more and read more: In addition to classroom study, you can also expand your knowledge and horizons by attending classes and reading extracurricular books. This can improve their comprehensive quality and cultural accomplishment. Cultivate interest: the best motivation for learning is interest, so try to cultivate your interest and love for the course. Only if you really like learning can you master knowledge and skills better.
