If you feel at home, as an N-year publicity committee member, I personally suggest setting up a paradise around the blackboard newspaper-collecting lovely photos of the whole class, or unifying all the photos with the same size to take funny and lovely photos, the best class teacher (* _ *) hee hee ..., if you don't need to take photos alone, it will better reflect the warmth and fun of your class. It's best to leave a place for the class photo, draw a little in the blank around the photo and doodle it, and it's OK.
Or hand in my childhood photos for everyone to guess. (everyone should be very cute when they were young! ! ! )
I once decorated a photographer and hung my classmates' own excellent works around the classroom (comics, calligraphy, hand-painting, anyway, all talented students in the class should not let go and let them show themselves). We used to have a triangular podium near the podium, and I also asked many students in my class to bring their own handmade works (such as things made of waste products). If you don't want to show such things, all kinds of plants are quite warm), it will be good. I cross-stitch a clock and hang it on the blackboard. I can tell the time. It looks beautiful, but this one is much more expensive. If I show it myself, it will be more expensive to buy a finished product, probably around 80 yuan. If it is beyond my ability, you can not hang up, or buy a cheaper clock, or don't hang up at all. It's up to you.
I wonder if this suggestion can help you. I hope so. If you are not satisfied, you can ask supplementary questions, and I will try my best to help you o (∩ _ ∩) o. ...
